You can put this solution on YOUR website!
y=x^2-4x
y=x^2-4x [Factor and set each factor equal to zero]
0=(x)(x-4)
0=x
and
x-4=0
x=4
[Plug these values into the equation and solve for y; plot the points]
[Pick other values for x, solve for y and plot the points; graph]
.
y=-x+1
The y-intercept = (0,1)
The x=intercept =(1, 0)
The slope = (-1/1)
