A line that is parallel to another line will have the same slope, in our case, the slope of 3. Therefore, we can just change the y-intercept to create any line parallel to y=3x+5 (just remember to keep the slope the same). For example, y=3x+5, y=3x-9, and y=3x+6.2 are all equations that are parallel to y=3x+5.

Answer:
-7/2
Step-by-step explanation:
y2-y1 / x2-x1
-5-10 / -2-4
-15 / -6
-7 / -2
= -7/2
