Math ten points

nathan took his car in for service and repairs he had a coupon for 15 % off.

.labor $268.38
.parts $382.69
.other $68.34

which amount is closest to nathans total costs after the 15% discount and including 7% sales tax ? (assume tax is applied after the discount is applied)

B because u add 268.38+382.69+68.34=719.41 then u take 719.41-15%=611.4985

Where m is the slope of the line and b is the y-intercept of the line, or the y-coordinate of the point at which the line crosses the y-axis. to write an equation in slope-intercept form, given a graph of that equation, pick two points on the line and use them to find the slope. this is the value of m in the equation.

It's like discovering the answer to a puzzle. the purpose in solving an equation is to find the value or values of the variable that makes it a true statement. any value of the variable that makes the equation true is called a solution to the equation.
