B. Altitude
An altitude connects the vertex of a triangle with the opposite side creating a right angle
When they say to solve for a variable, they want you to isolate/get the variable by itself.
5.) Solve for b (get b by itself)
Multiply 2 on both sides to get rid of the 1/2
2A = bh Divide h on both sides

6.) Solve for r
Divide 2 and
on both sides

First find slope
(-5-1)/(-2+3) = -6/1 = -6
Y = -6x + b
Plug in any point
1 = -6(-3) + b
1 = 18 + b, b = -17
Solution: y = -6x - 17
The letter answer would be B
Answer:
<h2>length = 44 in, width = 20 in</h2>
Step-by-step explanation:

Y=-2x+5
The standard form is y=mx+b, since m is the slope you would put -2 in substitute for it and since (0,5) has a zero as the x and a number as the y that gives you the b which is the y-intercept.
