Answer:
y = -x - 1
Step-by-step explanation:
1. The slope-intercept form of any linear equation is y = mx + b, where y = y-coordinate, m = slope, x = x-coordinate, and b = y-intercept.
2. To find the slope given two points, we can use the formula and plug in the corresponding variable.
3. Okay, so the slope is -1x or just -x. This means that the equation looks like this so far: y = -x + b
4. To find b, the y-intercept, we can take the equation of and plug in the values!
5. Now that we have our y-intercept and slope, let's plug in those values and find the equation!
Therefore, the equation of the line is y = -x - 1. I hope this helped you!
The school can charge $7.54 for each agenda book.
Step-by-step explanation:
Given,
Purchase price of 350 books = $1137.50
Profit they want to make = $1500
Total amount = 1137.50 + 1500 = $2637.50
Therefore;
The school must sell 350 books for $2637.50
Thus,
350 books = 2637.50 dollars
1 book =
1 book = $7.535
Rounding off to nearest cent
1 book = $7.54
The school can charge $7.54 for each agenda book.
