Answer:
y = 5x - 3
Step-by-step explanation:
As we move from the point (-2, -13) to the point (1, 2), we see the x-value (the 'run') increasing by 3 and the y-value (the 'rise') increasing by 15. Therefore the slope of the line passing thru these two points is m = rise / run = 15/3, or m = 5.
Using the slope-intercept formyula y = mx + b, we find the y-intercept as follows, using 1 for x, 2 for y and 5 for m:
2 = 5(1) + b, or
b = -3
Then the desired equation is
y = 5x - 3

Answer:
1000 : 199 : 271
Step-by-step explanation:
A rations a form of comparison between different variables or quantities.
We want to compare how much water, sucrose and saline solution are used to make the medicine.
The amount of water used is 1 L = 1000 mL
The amount of sucrose used is 199 mL
The amount of saline solution used is 271 mL
Therefore, the ratio of water to sucrose to saline solution is:
1000 : 199 : 271
This is the simplest form because 1000, 199 and 271 do not have any common factors.
7.89 percent, subtract 10.25-9.50 you get . 70 and then convert to fractions
Answer:
Slope: 1
Y-intercept: (0,3)
Step-by-step explanation:
The y intercept is when the slope reaches the y-axis line. In this case, it is given to us. Anything that is formed like this: (0, y) is the y-intercept.
Y intercept: (0, 3)
For slope, you can use the formula rise over run.
From the picture, I have drawn the rise over run, which is , which is also 1.
Slope: 1
Hope this helped.
