7%2Ax-2%2Ay=-5 Start with the given equation

Let's find the x-intercept

To find the x-intercept, let y=0 and solve for x:
7%2Ax-2%2A%280%29=-5 Plug in y=0

7%2Ax=-5 Simplify

x=-5%2F7 Divide both sides by 7



So the x-intercept is (note: the x-intercept will always have a y-coordinate equal to zero)

7%2Ax-2%2Ay=-5 Start with the given equation

Now let's find the y-intercept

To find the y-intercept, let x=0 and solve for y:
7%2A%280%29-2%2Ay=-5 Plug in x=0

2%2Ay=-5 Simplify

x=-5%2F-2 Divide both sides by -2



y=5%2F2 Reduce



So the y-intercept is (note: the y-intercept will always have a x-coordinate equal to zero)

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

So we have these intercepts:
x-intercept:

y-intercept:
