Answer:
y = -x/4 + 7/2
Step-by-step explanation:
Find the slope
( -2 , 4) ( 6 , 2)
m = (y2 - y1)/(x2 - x1)
x1 = -2
y1 = 4
x2 = 6
y2 = 2
m = ( 2 - 4)/( 6 -(-2)
m = ( 2 -4)/(6 +2)
= -2/8
= -1/4
Using point slope form equation
y - y1 = m( x - x1)
Using the second point
( 6 , 2)
x1= 6
y1=2
m = -1/4
y - 2 = -1/4(x - 6)
y - 2 = -(x - 6)/4
Open the bracket with -
y - 2 = (-x + 6)/4
y = ( -x + 6)/4 + 2
LCM = 4
y =( -x + 6 + 8)/4
y = (-x + 14)/4
Rearrange using slope intercept form
y = mx + c.
y = -x/4 + 14/4
We can break 14/4 by dividing by 2
y = -x/4 + 7/2
Answer:
C. ⅓
Step-by-step explanation:
A function in slope-intercept form is written as 
Here, b represents the y-intercept.
So given the function, 
, the y-intercept (b) would obviously be ⅓.
y-intercept = ⅓
The one missing is the fourth choice.
As you can see, the x axis stands for the weight, and the y axis the total cost.
You can see that the point, (1, 4) definitely exists.
So basically it would be 1 pound of cheese for four dollars, since x is weight and y is total cost.
You can see the fourth choice states that it's four dollars for one pound of cheese.
Hope this helped :)
