Question

Write an equation in slope-intercept form for the line that satisfies the following condition.
slope 4, and passes through (2, 20)

Answer 1

y=mx+b, mis the slope and b is the y-intercept

Answer 2

substitute y and x into y=mx+b to find the value of b

Answer 3

put in all the values that you have been given:
m=4
x=2
y=20

y=mx+b
20=2(4)+b
20=8+b
12=b

y=4x+12
