<PRE><B>Question 949546</B>
y=mx+b You have x and y given, plug them in with your calculated m and solve.
If m=15 is correct:
y=15x+b Using 250 and $7150:
$7150=15(250)+b Subtract 15(250) from each side.
$7150-15(250)=b
3400=b
CHECK with the other:
y=15x+b Using 310 and $8050
$8050=15(310)+b
$8050-15(310)=b
3400=b
ANSWER: The equation is y=15x+3400.
