Question

A line contains the point (2,1) and has a slope of -2. what is the equation

Answer 1

Answer:

The equation of this line would be y = -2x + 5

Step-by-step explanation:

To find any line given a slope and a point, use the base form of point-slope form and plug in the known values. Then solve for y.

y - y1 = m(x - x1)

y - 1 = -2(x - 2)

y - 1 = -2x + 4

y = -2x + 5
