Answer:
a) y = 6x - 3
b) 1/3y = 2x -1
The first thing you need to do is isolate (y) in the second equation
3 x (1/3y) = 3 x (2x - 1)
y =6x - 3
After isolating (y) in equation b they end up being the same.
Graphing:
In order to graph this, you have to make the first point at (0, -3) since this is the Y-intercept of the equation.
In order to graph the other points, you must move 6 units up and 1 unit to the right. Or vise versa If you need a visual I'll gladly link one.

Answer
2.5q
Explanation
Product means multiplication
(q × 5)/2 = (5q)/2
= 2.5q
Answer:
1. m = -4
2. y - 13 = -4(x + 8)
3. y - 9 = -4(x + 7)
Step-by-step explanation:
Slope m = (y2-y1)/(x2-x1)
m = (9 - 13)/(-7 - -8) = -4/+1 = -4
The point slope formula using (-8,13):
y - 13 = -4(x- -8) => y - 13 = -4(x + 8)
The point slope formula using (-7,9):
y - 9 = -4(x - -7) => y - 9 = -4(x + 7)
