Answer:
y=5x+10
Step-by-step explanation:
Use two points from the table: (1, 15) and (2, 20) to find m (m=[tex]\frac{y_2-y_1}{x_2-x_1}[/tex])
m=[tex]\frac{20-15}{2-1}[/tex]
m=5
Use another point from the table as x and y: (25, 3) in the equation y=mx+b (we just found m=5). Solve for b
y=mx+b
25=5(3)+b
10=b
Therefore, knowing m and b the equation in slope intercept form is:
y=5x+10
