Answer:
y= 5/2x - 5
Step-by-step explanation:
First, use the equation y=mx+b
m = the slope (5/2)
x = the x coordinate: 4
y = the y coordinate: 5
Then plug in for the values and solve for the only unknown, b.
Therefore we have:
5 = (5/2)4 + b
5 = 10 + b
5 - 10 = b
b = -5
Revert to original equation:
y = 5/2x - 5
