Let's take the first 2 x and y values and use them. First, you need to fill in your formula: y2-y1/x2-x1. It should look like this: 5-2/4-2. Then solve and you should get 3/2. You can't simplify it. So, this is your slope.
Next, you need to put this is into another formula. The formula is y-y1=m(x-x1). Take the first coordinate pair and plug it in for x1 and y1. Plug in your slope for m. When it's filled in, you should have y-2+3/2(x-1). It's hard to explain how to solve it so i'll just write it out.
y-2=3/2(x-2)
y-2=3/2x-3
y=3/2x-1
So, we have our equation in slope intercept form so that we have our slope and our y-intercept.
Y-intercept: -1
Slope: 3/2
Please put this as brainliest it took awhile and I hope this helped :) reply with questions if you still need help or have questions about the steps
The number of computers increased by 38.9%
Step-by-step explanation:
Number of computers at start of week = Old value = 18
Number of computers by end of week = New value = 25
Change = New value - Old value
Change = 25-18 = +7
The positive sign indicates the increase.
Increase percent = 
Rounding off to nearest tenth
Increase percent = 38.9%
The number of computers increased by 38.9%

Answer:
$186.2
Step-by-step explanation:
38 kg costs $144.40
∴ 1 kg costs = 
= $3.8
49 kg costs = 3.8 x 49
= $186.2
Answer:
Step-by-step explanation:
For 
the set of points that include all solutions are 
such that ; then we have 
.
What is important to stress here is that represents all of the solutions, while other points that we are given represent one solution (for example, point (2,-1) is just one solution)
220 (divide sign) 5 = 44ml (change it to liters) 0.044 (move the decimal from 44.0 their by two spots so it would be 0.044)
