Question

Find the equation of the line which passes through to (2,-1) and slope is 3

Answer 1

Answer:

The point slope form of the line would be y + 1 = 3(x - 2) and the equation of the line would be y = 3x - 7

Step-by-step explanation:

To find the point-slope form of the line, start with the base form of point-slope form. Then input the point we have and the slope in the appropriate places.

y - y1 = m(x - x1)

y - -1 = 3(x - 2)

y + 1 = 3(x - 2)

Now to find the slope intercept form, you simply  need to solve for y.

y + 1 = 3(x - 2)

y + 1 = 3x - 6

y = 3x - 7
