Answer:
-m+4
Step-by-step explanation:
Answer:
- m = -3/4
- y-intercept = 399
- slope-intercept equation: y = -3/4x + 399
Step-by-step explanation:
It can be easiest simply to solve the equation for y.
3x + 4y = 1596
4y = -3x + 1596 . . . . subtract 3x
y = -3/4x + 399 . . . . divide by 4
From this equation in slope-intercept form you can read the slope as -3/4 and the y-intercept as 399. You already know the equation.
Answer: he sold 9 pairs of dress shoes.
he sold 4 pairs of athletic shoes.
Step-by-step explanation:
Let x represent the number of pairs of dress shoes that he sells.
Let y represent the number of pairs of athletic shoes that he sells.
The total number of pairs of shoes that he sold in a day is 13. It means that
x + y = 13
The salesman receives a commission of $4 for every pair of dress shoes he sells. He is paid $3 for every pair of athletic shoes he sells. The commission that he got on that day was $48. It means that
4x + 3y = 48- - - - - - - - - - 1
Substituting x = 13 - y into equation 1, it becomes
4(13 - y) + 3y = 48
52 - 4y + 3y = 48
- 4y + 3y = 48 - 52
- y = - 4
y = 4
x = 13 - y = 13 - 4
x = 9
1. y = 4x + 9 ; m = 4 ; b = 9
the slope is 4 because there’s a pattern of +4 going down the function table in the “y” column
and b= 9 because at the number 0 on the x line has 9 in the y box
2. y = 3x - 1 ; m = 3 ; b = -1
basically the same thing as the first one just different numbers
