Question

Find equation of the line that passes through the point a and point b

A=(4,7) B=(
2,3)

Answer 1

y = 2x - 1

Explanation:

A = (4,7)

B = (2,3)

Use slope formula
`((y2 - y1))/((x2 - x1))`:

`(3 - 7)/(2 - 4)`

`(-4)/(-2)`

2 is our slope

Solve for b by plugging in both values for either coordinate or A and B. I will use coordinate B for this answer.

y = 2x + b

3 = 2(2) + b

3 = 4 + b

-1 = b

Our final equation is [y = 2x - 1]
