slope-intercept form:

y = 2x + 7

Point-slope form:

y - 9 = 2( x - 1 )

I'm not 100% sure on the point slope form but try it for now.

point slope form

y-y1 = m(x-x1)

y-9 = 2(x-1)

change to slope intercept form

y-9 = 2(x-1)

distribute

y-9 = 2x-2

add 9 to each side

y = 2x-2+9

y = 2x+7

Answer:

y = -3x - 2

Step-by-step explanation:

Equation of a line passing through $(x_1,y_1)$ and slope m is,

$y-y_1=m(x-x_1)$

Slope of a line passing through $(x_1,y_1)$ and $(x_2,y_2)$ is,

Slope = $\frac{y_2-y_1}{x_2-x_1}$

Slope of the line passing through (0, -2) and (1, -5) will be,

Slope = $\frac{-2+5}{0-1}$

m = - 3

Therefore, equation of the line passing through (0, -2) and slope = -3 will be,

y + 2 = -3(x - 0)

y + 2 = -3x

y = -3x - 2
