Answer:
Y = 2x - 15
Step-by-step explanation:
You have to memorize point-slope form. Here it is:
y - y1 = m(x - x1)
Here's what you gave me:
M = 2
(x1 = 4, y1 = -7)
The x1 and the y1 are the point on the line, and the M is the slope of the line.
We now substitute.
y - (-7) = (2) (x - 4)
Now you simplify it.
Multiply the 2 to each value in parenthesis.
Y + 7 = 2 (x - 4)
Y + 7 = 2x - 8
Isolate the Y by moving -7 over.
Y = 2x - 15
