Find the equation of the line that contains the given point and is perpendicular to the given line. Write the equation in slope-intercept form, if possible, (-7,-1);y=-7x+9

expression #3 is not equivalent. the others are.

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1

or

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
