Question

What equation of a line that passes through (7, 8) and has a slope of -3?

Answer 1

Answer:

The equation of this line is y = -3x + 29

Step-by-step explanation:

In order to find this, start with the basic form of point-slope form.

y - y1 = m(x - x1)

Now put the slope in for m and the point in for (x1, y1)

y - 8 = -3(x - 7)

Now solve the equation for y.

y - 8 = -3x + 21

y = -3x + 29
