Question

Choose 1 set of points from the choices below. Then, solve the problem and post your solution, showing your steps.

Write an equation in point-slope form for the line that passes through one of the following pairs of points (you may choose the pair you want to work with). Then, use the same set of points to write the equation in standard form and again in slope-intercept form.

Point pairs

(5, 1), (–3, 4)

(0, –2), (3, 2)

(–2, –1), (1, 2)

I chose the last one. For slope-intercept form, I have y = 1x + 1. For point-slope form, I have y + 1 = 1(x + 2). For standard form, I have 1x - y = -1.

Could you please check if my answers are correct?

Answer 1

looks good to me, though why you bother with the 1x notation is unclear.
