At what point does the line given by the following equation cross the x-axis?
y = -x + 7

(7, 0)

Step-by-step explanation:

We are trying to find the location that the equation crosses the x-axis.

This location is also known as the x-intercept.

To find the x-intercept, you can just set y in the equation to 0 and then solve for x.

0 = -x + 7

-x = -7

x = 7

So, the x-intercept is 7.

X-intercepts always have a y of 0 by definition, so it can be found at the point (7, 0)

do you mean add both of the equations together

because if you do the answer is 10x-5
