B. Starting with the fact that angles 1 and a are a linear pair and that angles b
and 2 are also a linear pair, use a two column proof to prove that
consecutive interior angles a and bare supplementary (5 points)
Statement
Reason

Abit confused about what you mean, but i think you might be referring to slope intercept form: y = mx + bin that case b, or the y intercept is already given.(0,-1)find the slope by using the formulay2 - y1/x2 - x1the final slope will be 4/2, equivalent to 2.now your equation should look like thisy = 4/2x -1sorry if this didn’t you out!
