Answer:

No.

Step-by-step explanation:

Given two equations:

  1. -x + 4y = -9 ___(i)
  2. y = -2x + 6 ___(ii)

Substitute (ii) into (i):

-x + 4(-2x+6) = -9

-x - 8x + 24 = -9

-x - 8x = -9 - 24

-9x = -33

x = -33/-9 = 33/9 = 11/3 = 3.67

y = -2(11/3) + 6 = -4/3 = -1.33

Solution: (11/3, -4/3) or (3.67, -1.33)
No

How to get solution:
Change first into slope intercept form
-x+4y=9
4y=-x+9
y=1/4x+9
Second is already in slope intercept form, so graph both and find the intersection. The intersection is (3.667, -1.333)
