Answer:
y = 5x + 15
Step-by-step explanation:
the y intercept is 15 because that is the about that will initially be paid no matter how much or how little you swim, and the slope is five because the amount paid in all is determined by how much he swims. hope this helps :)
(3, -7) and (-1, 1)
To find slope of a line using 2 points
we use formula
(3, -7) is (x1,y1) and (-1, 1) is (x2,y2)
Here x1= 3 and y1= -7
x2=-1 and y2=1
=-2
slope of a line using 2 points (3, -7) and (-1, 1) is -2
