Question

Determine the slope, m, and y-intercept, b, of a line that passes through the points (–2, 6) and (4, –3).

Answer 1

`y = - (3)/(2) x + 3`

slope is -3/2, y-intercept is 3.

Explanation:

`m = ( - 3 - 6)/(4 - ( - 2)) = ( - 9)/(6) = - (3)/(2)`

`6 = - (3)/(2) ( - 2) + b`

`6 = 3 + b`

`b = 3`

`y = - (3)/(2) x + 3`
