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

Step-by-step explanation:

The slope of the line is $\frac{7-3}{3-1}=\frac{4}{2}=2$

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

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