Question

(3,20) with a slope of 4

Answer 1

Answer:

y = 4x + 8

Step-by-step explanation:

The slope intercept form for an equation is y=mx+b, where m is the slope and b is the y-intercept (the value of y when x = 0).

m, the slope, is 4

y = 4x + b

We need a value of b that will force the line through point (3,20).  Enter that point in the above equation and solve for b:

y = 4x + b

20 = 4*(3) + b for (3,20)

20 = 12 + b

b = 8

The equation becomes y = 4x + 8
