Answer:
y = (-7/5) x + 15
Step-by-step explanation:
Let's name the line whose formula we'll calculate as line A. The other line is line B.
<u>Rewrite the equation of line B</u>:
- 7x+5y=3
- y = -7x/5 + 3/5
A parallel line has to have the same slope (-7/5). With that information in mind, we only need to calculate b (following the basic equation for a line, y=mx+b).
Line A passes through the point (5,8), so we can express the slope as:
- m =
So we solve for y₁:
- 8-y₁ = -7
- y₁ = 15
That is the value in the Y-axis line A crosses when x=0. In other words, it is b.
The equation is y = (-7/5) x + 15
