M=5
Positive 5 because a negative divide by a negative is a positive
All you have to do is divide 45 and 9

Answer:X=5

Step-by-step explanation:-9m=-45

First divide both sides by 9. The 9 will cancel out and you'll be left with 5 because of -45 divided by -9.The reason on why its positive is because a negative divided by a negative cancels out and becomes positive.

Question 8 of 10

Answer:

y = (-3/7)x + 2

Step-by-step explanation:

slope-intercept form is y = mx + b, where m = slope and b = y-intercept.

all you need to do is plug the values into the equation! :)

since your slope is (-3/7), plug that in for m.

y = mx + b ⇒ y = (-3/7)x + b

and since your y-intercept is 2, plug that in for b.

y = (-3/7)x + b ⇒ y = (-3/7)x + 2

therefore, the line's equation in slope-intercept form is y = (-3/7)x + 2.

don't worry about the parentheses, i only put them in there to separate the 7 in -3/7 from x. i'm not good at putting equations in here on brainly lol i just wanted to make sure you didn't think that it was -3 over 7x.

i hope this helps! have a lovely day <3

same as before, is the proportion of one, the same as the other? let's do the same here without much fuss.
