Answer:
y = 1.2x + 770
Step-by-step explanation:
y = m*x + b
Equation One
y = mx + b
1370 = m*500 + b
Equation Two
y = mx + b
1730 = m*800 + b
Solution
1730 = 800*m + b
1370 = 500*m + b Subtract. The b's cancel
360 = 300 * m Divide both sides by 300
360/300 = m
1.2 = m
Now use the second equation to solve for b
y = 1730
x = 800
1730 = 1.2*800 + b
1730 = 960 + b Subtract 960 from both sides
b = 770
