Question

Find the equation for the linear function that passes through the points (−5,−4) and (5,2). Answers must use whole numbers and/or fractions, not decimals.
Use the line tool below to plot the two points.


State the slope between the points as a reduced fraction.

State the y-intercept of the linear function.

State the linear function

Answer 1

Answer:

$y = \frac{3}{5} x - 1$

Step-by-step explanation:

1) find m or the slope:

$m = \frac{ - 4 - 2}{ - 5 - 5} = \frac{3}{5}$

2) plug in coordinate pair to solve for b:

$y = \frac{3}{5} x - b$

$2 = \frac{3}{5} (5) + b$

$b = - 1$

3) now you have m and b so you have your formula
