Answer:
the first one
Step-by-step explanation:
because x has an coefficient
To find the slope, you use the slope formula(m):
And plug in the two points
(-18, -28) = (x₁, y₁)
(-15, -37) = (x₂, y₂)
[usually we go from left to right, so whatever point is furthest to the right is the second point, and -18 is on the left of -15 on the x-axis, and slope is also: 
"run" being the number of units you go to the right, you can clarify with your teacher about it to be sure]
[two negative signs cancel each other out and become positive]
m = -3
