x = 5

y = -1

Step-by-step explanation:

from second equation,

  • y = -2 + 1
  • y = -1

by putting the value of y in first equation

  • y = -x + 4
  • -1 = -x + 4
  • -x = -1 -4
  • -x = -5
  • x = 5

x = 5 and y = -1

Answer:

C. The functions have the same y-intercept

Step-by-step explanation:

In slope intercept form, y = mx + b, b represents the y-intercept, and in the first function the y-intercept is 10.

The y-intercept is when x = 0, and in the chart, when x equals 0, y equals 10.

10 = 10, so they have the same y-intercept.
