Calculate the coordinates of the x-intercept & y-intercept of the linear equation:
3x + 4y = 24
Let x=0
4y = 24
(0,6) is the y-intercept
Let y=0
3x = 24
(8,0) is the x-intercept

The table represents a function that can be represented by a rule. Find the missing value.
Rule: y=4x
Answer: 20

Solve the proportion:
8/(x-3)=4/x
Cross multiply first step.
8x = 4(x - 3)
8x = 4x - 12
4x = -12
x = -3
200
Calculate m & b of the linear equation:
3y - 6x = -12
Add 6x both sides
3y = 6x - 12
Divide every term by 3
y=2x - 4
m= 2 & b= -4

Solve:
x/7-1=4
Add 1 to both sides first
x/7=5
x = 35

Each side length of the equilateral triangle ABC is 8 feet long. If the perimeter of triangle ABC is equal to the perimeter of the square below, solve for s.
4s = 24
s = 6

Write the equation of the line through the points (0,4) and (-4, 6)
m=(6-4)/(-4-0)=2/-4=-1/2
(0,4) is the y-intercept, thus b=4
y=-1/2x+4

The output of a function is 6 more than 2 times the input.
Solve for the input when the output is -10.
2x + 6 = -10
2x = -16
x = -8

The formula for the volume of a rectangular prism is given by
V=lwh
Solve for w.
Divide both sides by L & h
w=V/(lh)

Write the equation for the linear function f with the given values:
f(4) = 9 and f(-4) = -7
We have the solutions/coordinates of (4,9) & (-4,-7)
Find slope:
(-7-9)/(-4-4)=(-16)/-8=2
Plug in 2 for m and one of the (x,y) solutions to y=mx+b
9 = 2(4) + b
Solve for b. b = 1
Thus, y = 2x + 1
