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;
    }
  }
}
