Hey there!
On this problem, we have to combine like terms. A like term in this sense doesn't have to have the same coefficient, but it has to have the same variable.
Our like terms are 2m and 4m, along with 3 and 5.
When we add 2m and 4m we get 6m, and when we add 5 and 3 we get eight.
Notice how 5 and three are like terms because they're both whole numbers and don't have any variables.
Your solution is 6m + 8.
My advice to you is pay attention to your like terms and don't mix them up. A strategy is to underline like terms in the same color.
Hope this helps!
(5,-2)(-3,4)
slope = (4 - (-2) / (-3 - 5) = 6/-8 = - 3/4
y = mx + b
slope(m) = -3/4
use either of ur points...(5,-2)...x = 5 and y = -2
now we sub and find b, the y int
-2 = -3/4(5) + b
-2 = -15/4 + b
-2 + 15/4 = b
-8/4 + 15/4 = b
7/4 = b
so ur equation is : y = -3/4x + 7/4 <==
