Multiply the first equation by 2
2x + 2y =30
now we’ll add the second equation to the first equation
2x + 2y =30
-2x+5y= -2
7y=28
divide by 7
y=4
now plug y back into the first equation
x + 4 = 15
subtract 4
x=11

Answer:
6/2
Step-by-step explanation:
The slope is given by ...
slope = (y2 -y1)/(x2 -x1)
slope = (13 -7)/(4 -2) = 6/2
__
The value of the slope can be simplified to ...
slope = 3
