Answer:
Slope: undefined
Equation: x=-3
Step-by-step explanation:
To find the line that passes through the points, you first want to find the slope. The formula for slope is
. Once we have the slope, we can use any given point to plug in to find the y-intercept.

We can see that the slope is undefined. If we look at the point, we notice that they both have the same x-coordinate. This let's us know that the equation is x=-3.
Answer:
y = 5/2x
60 ft tall
Step-by-step explanation:
Substitute -1 for x. 3(-1)-1=-4.
(B)
Answer:
Step-by-step explanation:
you have two supplementary angles,
both added up=180
7y+5y=12y
12y=180y=15
angle DBC=7y=15*7=105
