Answer:

one way is to turn them into improper fractions then solve thwn like u would normally multiply/divide normal fractions and when u get ur answer change it back to mixed form

40xa^2 + 24 ax + 32 a =

all you have to do is factor out a 8a from each term
aka reverse distribution property

8a (5 a + 3x + 4)

Is it a, b , c , or d?

The line has a positive slope. Let's look at all the slopes:

1) -3

2) -3

3) 3

4)3

Which ones are positive? That's right, 3 and 4. We don't know which equation would be the equation of the line. That's where the other information comes in.

The line intersects the y-axis at at a point that has a negative y-coordinate. Lets write the last two equations in slope-intercept form.

1) y = -3/2x - 5/2

2) y = -3/2x + 5/2

We have to graph both of the lines now. The graphs are at the very bottom. Take a look at them. In the first one, the y-intercept is a negative and in the second one, the y-intercept is positive.

The third one AKA 3x + 2y = -5 is the equation of the line. I hope this helps! Let me know if I got it wrong or if you need any more help.
