Question

3. Write an equation in standard form that passes through the points (- 1, - 5) and (3, 7).

Answer 1

Explanation:

First you need to find the slope. Y1 - y2/m1-m2.

7--5=12 .....3--1=4

So 12/4=3 Your slope is 3.

Next the equation is y=mx+b.

Y= 3x+b. Then fill in y-coordinate and sole.

Use one from ordered pair. So 7 or -5 can be used.

Using 7

Y=3x+7 is your answer/equation.
