Question

Use graphing to find the x-coordinate of the solution to each system.

y=-x+4
y=-6x-6

A) -3
B) 2
C) -2
D) Infinite number of solutions

Answer 1

-2

Explanation:

plug both equations in desmos graphing calculator website

and you can see that the solution (where both equations intersect)

is (-2,6)

solutions are (x,y)

so the x coordinate of the solution is -2
