<h3>Answer: y = (3/2)x + 0</h3>
This is the same as y = (3/2)x
=============================================================
Work Shown:
Find the slope of the line through (x1,y1) = (-2,-3) and (x2,y2) = (2,3)
m = (y2 - y1)/(x2 - x1)
m = (3 - (-3))/(2 - (-2))
m = (3 + 3)/(2 + 2)
m = 6/4
m = 3/2
The slope is the fraction 3/2. This is going to be in front of the x, or to the left of the x.
----------
Plug m = 3/2 and (x1,y1) = (-2,-3) into the point slope formula. Solve for y.
y - y1 = m(x - x1)
y - (-3) = (3/2)(x - (-2))
y + 3 = (3/2)(x + 2)
y + 3 = (3/2)x + (3/2)(2)
y + 3 = (3/2)*x + 3
y + 3 - 3 = (3/2)*x + 3 - 3
y = (3/2)x + 0
The y intercept is zero. This matches up with the fact the graph crosses the y axis at y = 0.

Answer:
80
Step-by-step explanation:
If you add each value it equals 30.
30x10=300 so 8 (value of the 9th grade bar) times 10 equals 80.
Answer:
y = -x + 9.
Step-by-step explanation:
The slope = rise run
= 9 /-9
= -1.
The y intercept is at y = 9 so the equation is:
y = -x + 9.
Answer:
V =169.56
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h
V = 3.14 * (3)^2 * 6
V =169.56
