Write the equation of the line in SLOPE- INTERCEPT form: 1. (4, 2); slope 3
2. (3, -1); slope 4
3. (-4,-2), (4,0)

Step-by-step explanation:

1) slope = m = 3

(4 , 2) ;  x₁ = 4 ; y₁ = 2

y - y₁ = m(x  - x₁)

y - 2 = 3(x - 4)

y - 2 = 3x - 4*3

y - 2 = 3x - 12

y  = 3x - 12 + 2

y = 3x - 10     {Slope -intercept form: y = mx + b}

3) (-4 , -2) , (4 , 0)

We have to find the slope

m = 1/4  ; (4 , 0)

y - y₁ = m(x  - x₁)
