Answer:
y = (1/5)x + 7
Explanation:
Slope intercept form is y=mx + b where m is the slope and b is the y intercept.
We can see the intercept is 7.
so y = mx + 7
Let's calculate the slope using substitution. Pick a point. Let's use (5,8)
y = mx + 7
8 = m(5) + 7
1 = 5m
1/5 = m
so y = (1/5)x + 7
Another way to calc the slope is (y2-y1)/(x2-x1)
Pick 2 points. Let's use (5,8) and (10,9)
=(8-9)/(5-10)
=-1/-5
=1/5
Either way, y = (1/5)x + 7
