Question

Write the equation of the line that passes through each pair of points in slope-intercept form.
(0,-6) and (3,15)

Answer 1

\[Slope = m=\frac{ y2-y1 }{ x2-x1 } Slope intercept form= y-y1=m(x-x1) \]

Answer 2

\[slope= m= \frac{ 15-(-6) }{ 3-0 }=7 slope intercept form= y-15=7(x-3) \]

Answer 3

So, now 7 x (-3)= -21 and 7 x "x" = 7x
then y-15=7x-21
add the 15 to both sides +15 +15

Thus, the equation equals y=7x-6
