Question

Find the slope of the line through the points (0, -12) and (5, 3). (Write your answer in simplest form) *

Answer 1

Explanation:

(x₁, y₁) = ( 0 , -12) & (x₂ , y₂) = ( 5 , 3)

Slope =
`(y_(2)-y_(1))/(x_(2)-x_(1))\\\\`

`= (3-[-12])/(5-0)\\\\= (3+12)/(5)\\\\= (15)/(5)\\\\= 3`

(0 , -12) ; m =3

Equation: y - y₁ = m(x - x₁)

y - [-12] = 3 (x - 0)

y + 12 = 3x

y = 3x - 12
