Answer:
a. -2
b. s = 2 and y = -5
c. (2.5, -9)
d. -7x - 2
Step-by-step explanation:
a. In the image, I have used rise over run, which is -8/4 or -2.
b. slope formula is mx + b = y, where m is slope and b is the y-intercept. In the equation 2x - 5y = -10, 2 is the slope and -5 is the y-intercept.
c. Plug in all given numbers into an equation and the ones you do not have will be in the points you need it to be. Once you graph the equation you will receive (2.5, -9).
d. y = mx + b
5 = (-7)(-1) + b
5 = 7 + b
-2 = b
y = -7x - 2
0.37 meters of netting
<h3>Further explanation</h3><u>Given:</u>
Mrs. Nguyen used 1.48 meters of netting to make 4 identical mini hockey goals.
<u>Question:</u>
How much netting did she use per goal?
<u>The Process:</u>
We will solve the problem of conversion or in other words the ratio or proportion.
Option A: the conversion
Mrs. Nguyen used 1.48 meters of netting to make 4 identical mini hockey goals.
Then for every 1 goal, she needs 0.37 meters of netting.
Because
Option B: the ratio (or proportion)
In the ratio, we process as follows:
Both are divided by 4.
Thus, she uses 0.37 meters of netting per goal.
Alternative problem
How much netting did she use for 8 goals?
meters of netting.
We cross out eight and four because they can be divided.
She uses 2.96 meters of netting to make 8 identical mini hockey goals.
