What is the slope-intercept form equation of the line that passes through (1, 3) and (3, 7)?

y = −2x + 1
y = −2x − 1
y = 2x + 1
y = 2x − 1

find the slope
$\dfrac{7-3}{3-1}=\dfrac{4}{2}=2$

so the slope is 2x

now we find the y-intercept
$y=2x+b\3=2*1+b\2*1=2\3-2=1\b=1\y=2x+1$

Easy way.. will work just for this question.Substitute x coordinate in equations and chk the y that u get..whichever equation gives correct y is the answer.
