Question

Find an equation for the line with the given properties:

1) Containing the points (1, 3) and (-1, 2)

2) Slope = -2/3; containing the point (1, -1)

3) X-intercept = 2; y-intercept = -1

4) Parallel to the line 2x – y = -2; containing the point (-1, 2)

5) Perpendicular to the line y= 1/2 x + 4 containing the point (1, -2)

Answer 1

can you make no headway on any of them?
they are all just variations on

the line with slope m through (a,b) is

y-b = m(x-a)
