A line has a slope of - and passes through point
What is the equation of the line?

y-y1 = m(x-x1)

Step-by-step explanation:

if the slope = m

and it passes through the point (x1, y1)

you use the formula y-y1 = m(x-x1)

y-y1 = m(x-x1)

Step-by-step explanation:

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
