Answer:
Alright well to find the x-intercept, substitute in 0 for y and solve for x. To find the y-intercept substitute in 0 for x and solve for y
X-intercept: (9/13, 0)
Y-intercept: (0, 1/2) Hope this helps :)
Step-by-step explanation:
6x + 5y=-13
y=-7x+9
6x + 5(-7x +9) =-13
6x -35x + 45 = -13
-29x + 45 = -13
-45. -45
-29x = -58
/-29
x = 2
y = -7x + 9
y = -7(2) + 9
y = -14 + 9
y = -5

Wait is there any other information?
Step 1: Subtract 2x from both sides.
x−2x=2x−4−2x
−x=−4
Step 2: Divide both sides by -1.
−x−1=−4−1
x=4
Answer:
