Question

Independent practice write linear equations lesson 6

Answer 1

1)y=2x+7

2) unsure what the question is due to blur

3)y=3/4x-2

4)y=-2x

Answer 2

Explanation:

1) (1,9) ; slope = 2

Point slope form:

y - y₁ = m(x - x₁)

y - 9 = 2(x - 1)

Slope intercept form:

y - 9 = 2x - 2

y = 2x - 2 + 9

y = 2x + 7

3) (-4 , -5) ; slope = 3/5

Point slope form:

y - y₁ = m(x - x₁)

`y - [-5] = (3)/(4)(x - [-4])\\\\\\y + 5 = (3)/(4)(x + 4)`

Slope intercept form:

`y + 5 = (3)/(4)x + 4*(3)/(4)\\\\y + 5 =(3)/(4)x + 3\\\\y = (3)/(4)x +3 -5 \\\\\\y = (3)/(4)x - 2`
