Question

A line passes through (2, −1) and (4, 5).

Answer 1

The answer to the first problem is the top left corner because it is the only one with a -3 y-intercept and that's in the problem

To find the answer of the second problem you find the slope of the two points with the formula y2-y1 divided by x2-x1 and you just plug it in so 5+1 (the minus signs cancel out and turn into positives) divided by 4-2 and which is 6/2 which is 3 is your slope. then you could plug this information into a point slope form using either point I'm just going to choose the one with no negatives so plugging this in would be y-5=3(x-4) then you distribute the 3 and that gives you y-5=3x-12 then
                               +5       +5 add five to both sides of the equation and get
                             y=3x-7 and then you can put that into standard form which would be -3x+y=-7 and your answer would be the second one.
