Hi

y=-2x+2

7x+y=7  OR y = -7x + 7

Using the standard slope-intercept form for an equation of a line y = mx + b 

 where m is the slope and b the y-intercept to graph the lines:

 y = -2x + 2  |slope m = -2, y-intercept is Pt (0,2)  |Pt(1,0) another point

 y = -7x + 7  |slope m = -7, y-intercept is Pt (0,7)  |Pt(1,0) anther point

Plotting the y-intercepts and using their slopes to find another point on each line

connecting these points concludes the graphing

Note: these Lines have Pt(1,0) in common
