Answer:
The equation in the slope-intercept form will be:

Step-by-step explanation:
Given
As we know that the equation of a line in point-slope form is

substituting the values m = -5/4 and point = (8, -9)


Writing the equation in slope-intercept form

where m is the slope, and b is the y-intercept
so the equation of the line in slope-intercept form becomes

subtract 9 from both sides


Therefore, the equation in the slope-intercept form will be:

Q17:
one week = $560
52 weeks = 560 x 52 = $29120
Q18:
one year = $28500
52 weeks = 28500
1 week = 28500 ÷ 52 = $548
Q19:
5% of $300000 = 0.05 x 300000 = $15000
$15000 + $12000 = $27000
1. Distribute the Negative Signs
2. Combine like terms
-2x^2 + 12x-7
Just do 10.5 × 50 and whatever answer you get label as grams
