Question

What is the equation of the line that passes through (1, 3) and (-2, -3)?

Answer 1

Do you know the formula for equation of a line?

Answer 2

no

Answer 3

First thing is you have to find the slope

Answer 4

slope = second y value from the first y value / divided by the second x value from the first x value

Answer 5

once you have the slope, you can use plug that into the formula: y-y1=m(slope)(x-x1)

Answer 6

y = -2x + 1

y = 2x + 1 correct?

y = 1/2 x - 1

y = -1/2 x + 1
