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
