First you subtract 1500-450 = 1050
Then you divide 1050/1500 = .7
The parallel lines have the same slope.
The slope-intercept form: y = mx + b
m - a slope.
We have 6x + y = 4 |subtract 6x from both sides
y = -6x + 4 → m = -6.
The slope-point form:

We have m = -6 and (-2, 3).
Substitute:

<h3>Answer: 6x + y = -9.</h3>
Answer:

Step-by-step explanation:
Line d slope is 8/7, therefore the perpendicular is -7/8
