Find the point-slope equation for the line that passes through the
points (7, -21) and (-4, 23). Use
the first point in your equation,
y - [?] =
]

y+21=-4(x-7)

Step-by-step explanation:

y-y/x-x gives you the slope of -4

Plug in the numbers and you get your answer

1. d.90

2. e. none of these (80)

3. a. 0

4. b. 6

5. e. none of these (10)

6. a. 5

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .
