Question

What is the equation of the line through (4, 2) and (0, -2)?

Answer 1

Answer:

Slope Intercept Form

y=x-2

Step-by-step explanation:

Find Slope using equation below

$\frac{y2 - y1}{x2 - x1}$

Chose points I chose 2 as y2 and -2 as y2

4 is x2 and 0 as x1

$\frac{2 - ( - 2)}{4 - 0} = \frac{4}{4} = 1$

Slope is 1

now choose a point and plug it in for x and y and plug slope in Equation

$y = mx + b$

I chose (4,2)

$2 = 1(4) + b$

2=4+b

subtract 4 by both sides

-2=b

Slope Form

$y = mx + b$

So... y=x-2 is the answer
