    how are you suppose to solve this by just looking at a graph?

    That will be the m in y=mx+b. To find the b, use the slope to figure out the y when the x is zero.

    put them all together and your equation is y=-2x+1

    can you try to do line 2 by yourself?

    and one of the points is (0,5) so the y-intercept is at 5 so the "b" is 5 so the slope-intercept form is y=-2x+5
