Answer:
<h2>• x=2y+9</h2>
Find the x-intercepts.
x-intercept(s):
(9,0)
Find the y-intercepts.
y-intercept(s):
(0,−9/2)
List the intersections.
x-intercept(s):
(9,0)
y-intercept(s):
(0,−9/2)
<h2>• 14x+2y=-54</h2>
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(s):
(−27/7,0)
y-intercept(s):
(0,−27)

Okay uh
x = 2y + 9
14x + 2y = - 54
14x + 2y = - 54
14(2y + 9) + 2y = - 54
28y + 126 + 2y = -54
30y + 126 = -54
- 126 -126
30y = -180
30y/30 = -180/30
y = -6
x = 2y + 9
x = 2(-6) + 9
x = -12 + 9
x = -3
(x, y) = (-3, -6)
