Question

16. What is the equation of the line that passes through the points (–2, 3) and (2, 7)? (4 points)

A. x – y = –1
B. x – y = –2
C. x – y = –5
D. x – y = –6

Answer 1

find the slope first

Answer 2

The equation of the line through points \((x_1, y_1) \) and \((x_2, y_2) \) is:

\(y - y_1 = \dfrac{y_2 - y_1}{x_2 - x_1} (x - x_1) \).

You are given two points.
Let
\(x_1 = -2\),
\(y_1 = 3\),
\(x_2 = 2\), and
\(y_2 = 7\).
Then substitute those values in the equation above and find the equation of the line.

Answer 3

then...
y=x+b

Answer 4

@eric_d
You mean y = mx + b, right?
