Question

What is the slope-intercept form equation of the line that passes through (1, 3) and (3, 7)? (1 point) y = −2x + 1 y = −2x − 1 y = 2x + 1 y = 2x − 1

Answer 1

Answer: y=2x+1

Explanation:

The slope of the line is
`(7-3)/(3-1)=(4)/(2)=2`

Using the point (1,3) to substitute into point-slope form,

`y-3=2(x-1)\\\\y-3=2x-2\\\\\boxed{y-2x+1}`
