Because we have x = 3, we can substitute it. But first, let's convert 2x + 4y = 14 into y-slope intercept form.

2x + 4y = 14
Subtract 2x from both sides.
4y = -2x + 14
Divide both sides by 4.
y = -1/2x + 3.5

Now substitute.

y = -1/2(3) + 3.5
y = -1.5 + 3.5
y = 2

Anne,Ryan and Joel collect empty cans for recycling. They collect a total of 1,925 cans. Anne collects half as many cans as Ryan
elixir [45]
A + R + J = 1925
A = 1/2R
J = 2R

1/2R + R + 2R = 1925
7/2R = 1925
R = 550

J = 2(550)
J = 1100

Joel collects 1100 cans.

Write the equation of the line that passes throught the point (-4,-9) and has a slope of 1/2
Ray Of Light [21]

Answer: y = 1/2x - 7

<u>Data</u>

Point = (-4, -9)

slope = m = 1/2

<u>Process</u>

To solve this problem, use the formula slope- y-coordinate, substitute the values and simplify.

<u>Equation</u>

 y - y1 = m (x - x1)

       x1 = -4

       y1 = -9

<u>Substitution</u>

y + 9 = 1/2 (x + 4)

<u>Simplification</u>

 y + 9 = 1/2x + 4/2

  y = 1/2x + 2 - 9

<u>Answer</u>

y = 1/2x - 7
