 * READ THE FOLLOWING DIRECTLY FROM A LINE IN STANDARD FORM OR SLOPE-Y-INTERCEPT FORM**
 * **SLOPE**
 * **Y-INTERCEPT**
 * **X-INTERCEPT**


 * When you begin with Y-Intercept form:**

Y-Intercept Form: y=mx+b Example: y=3/2x+5 Slope: 3/2, Y-Intercept: 5

Y=0, Solve for x: 0=3/2x+5 -3/2x=5 Move variables to the left of the equal sign and constants to the right.

3*(-3/2)x=2*d Multiply by 2 to get rid of fractions.

-3x=10 Divide by -3 to isolate x.

x= -10/3

x-intercept=-10/3, Slope (m)= 3/2, Y-Intercept=3

Standard Form: ax+by-c=0 Example: 3x+7y-4=0
 * When you begin with Standard Form:**

for Y-Intercept: 7y= -3x+4 7y/7=-3/7x+ 4/7 y=-3/7x+4/7 (y=mx+b)

Slope (m)= -3/7, Y-Intercept (b)= 4/7

Y=0, and Solve for x

0= -3/7x+ 4/7

3/7x=4/7

7*3/7x = 4*4/7

3x/3= 4/3 x=4/3 Slope (m)= -3/7, Y-Intercept (b)= 4/7, X-Intercept= 4/3
