x-intercept


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


x-5y=-4 Start with the given equation.


x-5%280%29=-4 Plug in y=0.


x-0=-4 Multiply -5 and 0 to get 0.


x=-4 Simplify.


So the x-intercept is .


------------------------------------------


y-intercept


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


x-5y=-4 Start with the given equation.


0-5y=-4 Plug in x=0.


-5y=-4 Simplify.


y=%28-4%29%2F%28-5%29 Divide both sides by -5 to isolate y.


y=4%2F5 Reduce.


So the y-intercept is .


Now let's plot the points and which are the x and y intercepts respectively.





Now draw a straight line through the plotted points to graph x-5y=-4.

It's a straight line, so you need 2 points.
Usually we solve for y, then pick values for x, find y, and plot the points.
For this one, I'd solve for x to avoid fractions.
x = 5y - 4

Pick 2 values for y and find x.
y = 0;x = -4 --> (-4,0)
y = 1;x = 1 ---> (1,1)
---
Plot the 2 points, draw a line thru them.
