x-intercept


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


2x+%2B+y+=+70 Start with the given equation.


2x+%2B+0+=+70 Plug in y=0.


2x+%2B+0+=+70 Simplify.


2x=70 Multiply.


x=%2870%29%2F%282%29 Divide both sides by 2 to isolate x.


x=35 Reduce.


So the x-intercept is .

y-intercept


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


2x+%2B+y+=+70 Start with the given equation.


2%280%29+%2B+y+=+70 Plug in x=0.


0+%2B+y+=+70 Multiply 2 and 0 to get 0.


+%2B+y+=+70 Simplify.


So the y-intercept is .
