x-intercept


To find the x-intercept, plug in y=0 and solve for x


y=4x-7 Start with the given equation.


0=4x-7 Plug in y=0.


-4x=-7 Subtract 4x from both sides.


x=%28-7%29%2F%28-4%29 Divide both sides by -4 to isolate x.


x=7%2F4 Reduce.


So the x-intercept is .

y-intercept


To find the y-intercept, plug in x=0 and solve for y


y=4x-7 Start with the given equation.


y=4%280%29-7 Plug in x=0.


y=0-7 Multiply -4 and 0 to get 0.


y=-7 Simplify.


So the y-intercept is .
