Answer 1

Dave receives a salary of $200 a week plus a commission of 10% of his weekly sales. An equation y = mx + b represents Daveu2019s weekly earnings. The y-intercept is Dave's base salary. The slope of the line is his commission. Write an equation representing Dave's weekly earnings.

Answer 2

you are given the format y = mx + b where m is the slope (commission) and b is the base salary.
it's not directly stated, but if we let x = weekly sales, then we can simply replace m with the commission (10% of 0.10) and replace b with the base salary to write the equation
