Point slope form:
y - y1 = m(x - x1) where m = slope and coordinate point (x1, y1)
In this case y+2= 3(x-7), slope = 3 and a coordinate point (7, -2)
Answer is D
The slope is 3 and (7, 2) is on the line
The answer is 14.45. Hope this helps
Answer:
Any real number.
Step-by-step explanation:
I dunno what you're asking, but Im assuming you need what a equals to.

The answer is any real number.
Answer:
126 degrees
Step-by-step explanation:
Triangle: y = 180 - (5x + 4x)
Straight angle: y = 180 - (4x + 30)
180 - (5x + 4x) = 180 - (4x + 30)
5x + 4x = 4x + 30
5x = 30
x = 6
Angle:
y = 180 - (5x + 4x)
y = 180 - 9x
y = 180 - 9(6)
y = 126
