We can solve this by using the slope-intercept form of a line y=mx+b. We know that the slope (m) is 5/8, and the problem has given us a point. We can plug in the x and y value from the point along with the slope to find the y-intercept (b):
y=mx+b
-3=(5/8)(2)+b
-3=5/4 + b
b= -5/4-12/4 *remember we need a common denominator to add/subtract fractions
b= -17/4
