Answer: Perpendicular</h3>
=========================================================
Work Shown:
Solve the first equation for y
3x+7y = 15
7y = -3x+15
y = (-3x+15)/7
y = (-3/7)x + 15/7
The slope here is -3/7
-------
Solve the second equation for y
7x-3y = 6
-3y = -7x+6
y = (-7x+6)/(-3)
y = (7/3)x - 2
The slope here is 7/3
-------
The slopes -3/7 and 7/3 are not equal, so we don't have parallel lines.
The lines however are perpendicular because the slopes multiply to -1
(-3/7)(7/3) = (-3*7)/(7*3) = -21/21 = -1

Answer:
y=30
Step-by-step explanation:
f(-2)=18+3(-2)^2
f(-2)=18+3*4
f(-2)=18+12
f(-2)=30
Slope = y2-y1 / x2-x1
= 24-19/9-4
= 5/5
= 1
solve for b
y=1x+b
19=1(4)+b
19=4+b
15=b
the equation of the line is y=x+15
