You can put this solution on YOUR website!
y=-5x%2B1+...here you have a linear function; so, the graph will be a line
to graph a line you need two points to plot on the Cartesian coordinate system
easiest way to find these points is to set x=0 and find y which will be y-intercept, and to set y=0 and find x which will be x-intercept
y=-5x%2B1+...if x=0, y will be:
y=-5%2A0%2B1+
y=1+
so, y-intercept is at (0,1)

y=-5x%2B1+...if y=0, x will be:
0=-5x%2B1+
5x=1+
x=1%2F5+
so, x-intercept is at (1%2F5,0)
now you are ready to plot these points on the Cartesian coordinate system and draw a line through
