Answer:

Step-by-step explanation:
We can write the equation of a line in 3 different forms including slope intercept, point-slope, and standard depending on the information we have. We have a point and a slope from the equation. We will chose point-slope since we have a point and can find the slope.
Point slope:
We must find the slope using the slope formula.
Slope:
We substitute
and 


in our new equation because it is perpendicular to it. This means we will need to change it into its negative reciprocal which is
.
We will substitute
and
.

This is the equation of the line perpendicular to the equation line through the points given that crosses through (14,8).
Answer:
162 ft^2
Step-by-step explanation:
18 * 18 = 324
324/2 = 162
The area of the patio is 162 square feet
Answer:
D: y = 2x - 2
Step-by-step explanation:
1.
= 2
2. y = 2x + b
3. Insert the points into the equation: 8 = 10 + b
4. b = -2
5. y = 2x - 2
Answer:
The answer rewritten is y=x-3+x+2-x-5=x-6
