First find slope
(Y2-y1)/(x2-x1)
(-3-(-1))/(-6-9) = -2/-15 = 2/15
Point slope: y-y1 = m(x-x1)
Solution: y + 1 = 2/15(x - 9)

Someone help me please?! Math problem!!!
Gala2k [10]

Answer:

y  = 4/5x  - 9/5

Step-by-step explanation:

4x - 5y = 9  to solve for y you get it by itself.

-4x          -4x   minus 4x from both sides

-5y  = - 4x + 9

/-5            /-5   Divide both sides by 5

 y  = 4/5x  - 9/5   because -4/-5 is 4/5 and 9/-5 is - 9/5

What is four over nine equal A over 45
QveST [7]
Answer: A = 20


How to Solve:

Just by looking at this problem I can tell that the denominators (9 an 45) are factors of 9. So the second equation is multiplied by 5 from the first equation.

4/9 x 5

4 x 5 = 20
— -—
9 x 5 = 45

So A would be 20.


Another way to solve this would be by multiplying the 1st equations numerator with the second equations denominator:

4 x 45 = 180

Then divide 180 with the 1st equation’s denominator.

180 / 9 = 20

A = 20
