The slope-intercept form: y = mx + b
We have the slope m = 9, therefore: y = 9x + b.
Next. We have the table:
x | -5 | -2 | 1 | 3 | 4 |
y |-46|-19| 8 |26|35|
(1, 8) → x = 1, y = 8
substitute the values of x and y to the equation:
8 = 9(1) + b
8 = 9 + b |-9
b = -1
Answer: y = 9x - 1 → y-intercept is -1.
Starting price is : $248.50Price with 25% off :$248.50 x ( 1 - 0.25 ) = $248.50 x 0.75 = $186.375After that she has to pay 5 % sales tax:$186.375 x 1.05 = $195.70Answer: $195.70
