3 0

Since we know the slope is 3 we have part of the equation already (y=3x+b). Now we need to find the y-intercept. To do that we plug in the point that was given to us in the question and solve for b.

0=3(-5)+b
0=-15+b
15=b

Now that we have the y intercept we can put the equation together.

Answer: y=3x+15

Hope this helps :)

Ronch [10]

$\32a^3b^2 \ , \ 44ab^3 \ , \ 40a^2b\\
$

$\text {Taking out common factor : } \\ \\
4ab(8a^2b) + 4ab(11b^2) + 4ab(10a)$

$\text { greatest common factor = } 4ab$
