In order to graph y=-5%2Ax%2B5 we only need to plug in two points to draw the line

So lets plug in some points

Plug in x=0

y=-5%2A%280%29%2B5

y=0%2B5 Multiply

y=5 Add

So here's one point (0,5)




Now lets find another point

Plug in x=1

y=-5%2A%281%29%2B5

y=-5%2B5 Multiply

y=0 Add

So here's another point (1,0). Add this to our graph





Now draw a line through these points

So this is the graph of y=-5%2Ax%2B5 through the points (0,5) and (1,0)


So from the graph we can see that the slope is -5%2F1 (which tells us that in order to go from point to point we have to start at one point and go down -5 units and to the right 1 units to get to the next point), the y-intercept is (0,5)and the x-intercept is (1,0)


We could graph this equation another way. Since b=5 this tells us that the y-intercept (the point where the graph intersects with the y-axis) is (0,5).


So we have one point (0,5)





Now since the slope is -5%2F1, this means that in order to go from point to point we can use the slope to do so. So starting at (0,5), we can go down 5 units



and to the right 1 units to get to our next point


Now draw a line through those points to graph y=-5%2Ax%2B5


So this is the graph of y=-5%2Ax%2B5 through the points (0,5) and (1,0)
