Ok so, basically reflect the shape horizontally across the y - intercept. In the exact same position but reflected across. I’m not sure because I can’t really see the points. Does it give you options? Or do you have to type it?

Find the slope and y-intercept of 5x-y=-5
trasher [3.6K]
Slope is 5
Y intercept is 5

Solve:
5x-y=-5
(Isolate Y by adding y to both sides to get it alone and adding 5 to both sides)
Y=5x+5
We know that slope (m) is w the X so in this case it is 5
And then to find the y intercept we substitute O for X.
Y=5(0)+5
Y=5
