Question

Write an equation in point-slope form and slope-intercept form for each line.

1. passes through (4, 7), slope = 2
2. passes through (–2, –1), slope = 4
3. passes through (8, –4), slope = 1/2

Answer 1

y=2x-1

y-7=2(x-4)

2x-y-1

//

y=4x+7

y--1=4(x--2) = y+1=4(x+2)

4x-y+7

//

y=1/2x-8

y--4=1(x-8) = y+4=1(x-8)

1x-y-12
