Answer:
y = -2.5 x + 6.5
Step-by-step explanation:
The equation of a line in slope-intercept form is written as
y = mx + b where m is the slope and b is the y-intercept.
a) We can find the slope of the line passing through (-1,30 and (-4, 5) by subtracting the y coordinates and dividing the difference by the difference if the x coordinates:
m = (5 - 3 ) = 2
-4 - (-1) -3
Now use this slope and substitute the coordinates of either of the given points to find the y-intercept, b . Let's use (-1,3):
y = mx + b
3 = -2 • -1 + b
3
3= 2 + b
3
7 = b
3
The equation of the line will be y = -2 x + 7
3 3
b) Using y = mx + b, we can substitute -2.5 for the slope and use the point to find the y-intercept:
y = -2.5x + b
1.5 = -2.5 • 2 + b
1.5 = -5 + b
6.5 = b
The equation of the line will be:
y = -2.5 x + 6.5
Answer:
10 is maximum of packages of quesadillas.
Step-by-step explanation:
x= number of wings
y= number of quesadillas
x+y=20
8x+10y=$160
if x=7
then 7+y=20
20-7=14=y
14*10=140
8*7=56
Rasheed can't buy 20 packages, since it'll go over his budget.
So 160-56=104
And 104/10= 10 minimum
10*10=100
100+56=160
So he can buy 10 packages of quesadillas.
