Question

A line passes through the point (-2, 9) and has a slope of -3. Write an equation using the point-slope form for this. No Links. Thank you

Answer 1

Answer:

(y-9)=-3(x+2)

Step-by-step explanation:

yeah-ya..... right?

Answer 2

Answer:

y - 9 = -3(x + 2)

Step-by-step explanation:

Point-slope formula is named for the information that you can pick right out of the equation, that is a point on the line and the slope. It is:

y - y = m (x - x)

The m is the slope. They gave you that the slope is -3 so fill in -3 in place of the m.

The point you were given was (-2,9) the -2 is the x and the 9 is the y.

In the formula fill in the second y with 9 and fill in the second x with the -2.

Keep the first y and the first x (that's right inside the parenthesis) those stay as variables in your point-slope formula

It's literally a fill-in-the-blank problem.

y - 9 = -3(x + 2)
