Question

Which of the following is the correct point - slope equation for the line that passes through the point (-6,-1) and is parallel to the line given by y = 7x+31?

Answer 1

The answer is C

Explanation:

If the two lines are parallel then they have the same slopes, the equation of the first line is y=7x+31, then the slope of the line is 7. Now you have the slope of the second line and this line is passing through the point (-6 , -1) then we will use the form of the equation
`y-y1/x-x1=m\\y-(-1)/x-(-6)=7\\y+1/x+6=7\\y+1=7(x+6)` so the correct answer is C

Answer 2

The answer is letter C
