Start with the point slope form
y-y%5B1%5D=m%28x-x%5B1%5D%29
y-%28-2%29=7%28x-1%29Substitute values for point and slope
y%2B2=7%28x-1%29
y%2B2=7x-7Distributive property
y=7x-7-2Subtract 2 from both sides
highlight%28y=7x-9%29Slope-intercept form
Check your answer to make sure you didn't make any mistakes.
y=7x-9%29
-2=7%281%29-9%29
-2=7-9%29
-2=-2%29
True statement.
No mistakes.
