The slope is -7 and we are given the point (0,8)
Since the x value is 0, the y value is the y-intercept of the line, which is 8.
With this information, we can write the equation of the line in slope-intercept form, y = mx+b (where m is the slope and b is the y-intercept)
y = -7x + 8
Let me know if you need any clarifications, thanks!
first multiply the two terms together to find out how much money is being discounted
$70.50 x .47 = 33.135
now subtract that number from $70.50
$70.50 - 33.135 = $37.37
ANSWER: the discount is $33.14 & the sale price is $37.37
Pythagorean
Theorem as follows: A^2+B^2=C^2
