Answer:
y = 5x - 21
Step-by-step explanation:
Since we already know the slope, all we need to do is plug the values of x and y into the equation.
y = 5x + b
-1 = 5(4) + b
-1 = 20 + b
-21 = b
The equation is y = 5x - 21.
Answer:
Step-by-step explanation:
p = 106
L = 8 + 4W
p = 2L + 2W
p = 2(8 + 4W) + 2W
p = 16 + 8W + 2 W
p = 16 + 10W
106 = 16 + 10W
106 - 16 = 10W
90 = 10W
90/10 = W
9 = W
<h2>W = 9</h2><h2 />
L = 8 + 4W
L = 8 + 4(9)
L = 8 + 36
<h2>L = 44</h2>
44 + 44 + 9 + 9 = 106
44 * 9 = Area = 396
The two equations are

and

the first equation can be solved for x to be

next you can substitute x in the second equation

Distribute 4 to everything in the parentheses

combine like terms:

subtract 28 from both sides of the equation

divide both sides by -1.5

plug this in to the original equation of x+y=7

subtract 4 from both sides.

Answer:
y = -3.5x - 12
Step-by-step explanation:
Find the slope with rise over run: (y2 - y1) / (x2 - x1)
Plug in the points:
(9 + 5) / (-6 + 2)
14/-4
= -3.5
Then, plug this and a point into the equation y = mx + b to find b:
y = mx + b
9 = -3.5(-6) + b
9 = 21 + b
-12 = b
Then, plug this and the slope into the equation again:
y = mx + b
y = -3.5x - 12 will be the equation
