i'm having trouble actually hitting the planes and when i'm changing the loops it seems to affect the other loops can anyone tell me whats wrong

here is my code
im trying to make my shape increase in size when i press either mouse or key

void setup() {
  //set the size of the window
  size(800, 600);
  background(255);
  smooth();
}
void draw() {
  rect(pmouseX,pmouseY,mouseX,mouseY,mouseX,mouseY);
 strokeWeight(abs(pmouseX-pmouseY));;

}
void mousePressed(){
background(random(255),random(255),random(255));
stroke(random(255),random(255),random(255));
}
void mouseReleased(){
background(255);
}

void keyPressed(){
 fill(random(255),random(255),random(255));
}

void keyReleased(){
fill(255);
}

I am trying to draw  letters in processing right now i have  H and C but i cant do a V with slope i really need help.
Here is my code.

int x;
float y;
float slope;
float b;
int cSize;
int change;
boolean bInit;
int hStroke;
int cStroke;
int angle;
int radius;
int xCenter;
int yCenter;

void setup() {
  size(800, 600);
  background(255);
  bInit = true;
  cSize = 30;
  hStroke = 1;
  cStroke = 1;
  change = 3;
  angle=30;
  radius=75;
  xCenter=width/2;
  yCenter=height/2;
}

void draw() {
  switch (hStroke) {
  case 1:
    draw1stStrokeH();
    break;
  case 2:
    draw2ndStrokeH();
    break;
  case 3:
    draw3rdStrokeH();
    break;
  }
  switch (cStroke) {
  case 1:
    draw1stStrokeC();
    break;
  }
}

void draw1stStrokeH() {
  if (bInit) { // initialize
    bInit = false;
    x = 100;
    y = 100;
  }
  else { // draw
    ellipse(x, y, cSize, cSize);
    y = y + change;
    if (y > 300) {
      hStroke++;
      bInit = true;
    }
  }
}
void draw2ndStrokeH() {
  if (bInit) { // initialize
    bInit = false;
    x = 250;
    y = 100;
  }
  else { // draw
    ellipse(x, y, cSize, cSize);
    y = y + change;
    if (y > 300) {
      hStroke++;
      bInit = true;
    }
  }
}

void draw3rdStrokeH() {
  if (bInit) { // initialize
    bInit = false;
    x = 100;
    y = 185;
  }
  else { // draw
    ellipse(x, y, cSize, cSize);
    x = x + change;
    y = 185;
    if (x > 250) {
      hStroke++;
      bInit = true;
    }
  }
}
void draw1stStrokeC() {
  if (bInit) { // initialize
    bInit = false;
  }
    else { // draw
      float x; // local variable
      float y;
      x=xCenter+radius * cos(radians(angle));
      y=yCenter+radius * sin(radians(angle));
      ellipse(x, y, cSize, cSize);
      angle = angle + change;
      if (angle>310)
          cStroke++;          {
        bInit = true;
      }
    }
  }

i was taught how to do an letter N but since the Y axis is inverted i couldn't calculate the slope for  V.
this is the code for a Letter N
// initial N
int x;
float y;
float slope;
float b;
int cSize;
int change;
boolean bInit;
int nStroke;

void setup() {
  size(800, 600);
  background(255);
  bInit = true;
  cSize = 30;
  nStroke = 1;
  change = 3;
}

void draw() {
  switch (nStroke) {
  case 1:
    draw1stStrokeN();
    break;
  case 2:
    draw2ndStrokeN();
    break;
  case 3:
    draw3rdStrokeN();
    break;
  }
}

void draw1stStrokeN() {
  if (bInit) { // initialize
    bInit = false;
    x = 100;
    y = 100;
  }
  else { // draw
    ellipse(x, y, cSize, cSize);
    y = y + change;
    if (y > 300) {
      nStroke++;
      bInit = true;
    }
  }
}

void draw2ndStrokeN() {
  if (bInit) { // initialize
    bInit = false;
    x = 250;
    y = 100;
  }
  else { // draw
    ellipse(x, y, cSize, cSize);
    y = y + change;
    if (y > 300) {
      nStroke++;
      bInit = true;
    }
  }
}

void draw3rdStrokeN() {
  if (bInit) { // initialize
    bInit = false;
    slope = 200.0 / 150.0; // do not use 1.33
    b = -100.0 / 3.0; // do not use -33.3
    x = 100;
    y = slope * x + b;
  }
  else { // draw
    ellipse(x, y, cSize, cSize);
    x = x + change;
    y = slope * x + b;
    if (x > 250) {
      nStroke++;
      bInit = true;
    }
  }
}
