Complete the point-slope equation of the line through (-8,-8) and (-7,9)
y-9=__?__

Answer 1

The point-slope form:

`y-y_1=m(x-x_1)\\\\m=(y_2-y_1)/(x_2-x_1)`

We have the points (-8, -8) and (-7, 9). Substitute to the formula of a slope:

`m=(9-(-8))/(-7-(-8))=(17)/(1)=17`

Put the coordinates of the point (-7, 9) and the value of slope to the point-slope formula:

`y-9=17(x-(-7))\\\\\boxed{y-9=17(x+7)}`
