Complete the point slope equation of the line through (-9,6) and (-7,-8) use exact numbers

Hello!

Point-slope form is this: . In this form, m is the slope,   and is an ordered pair, or point.

To find the slope, we need to use the slope formula. The slope formula is: . We can assign the point (-9, 6) to and and (-7, -8) to and .

Now, we can substitute the ordered pairs into the formula and solve.

Since the slope is equal to -7, we can substitute the slope and a point into the point-slope form.

Therefore, your point-slope formula is y - 6 + -7(x + 9) or y + 8 = -7(x + 7).
