The letters in the equation
The number of stamps and the cost are illustrations of unit rates
40 stamps would cost $22
The cost of 15 postage stamps is $8.25
Start by calculating the unit rate of the stamps.
So, the number of stamps for $22 is calculated by dividing $22 by the unit rate.
So, we have:
Hence, 40 stamps would cost $22

y=4
the values of x changes while the y doesn't so it's y=4
Answer:
y = -2x -3
Step-by-step explanation:
I love slope-intercept form! lol
y =mx +b
so we have 2 points given: (-1,5) and (4,-5)
to find the SLOPE of the slope-intercept form, we need to subtract and divide
(-5-5)/(4+1)
-10/5= -2 which is our slope
now! lets translate this info into point slope form. y - y1 = m (x - x1)
(-1,5) and we kno the slope is -2.
y - 5 = -2 (x - (-1))
y-5 = -2(x + 1)
y-5 = -2x -2
add five
y = -2x -3 we are back to slope intercept form! YAY!
