Answer:
x-int = 18
y-int = -9/2
Step-by-step explanation:
Use slope-intercept form y=mx + b
To find the slope, substitute the two points into the slope formula and solve.
Substitute a random point (2,-4) and m=1/4 into slope-intercept form
y = mx+b
-4 = 1/4 (2) + b
-4 = 2/4 + b
-4 = 1/2 + b
Isolate b to solve
b = -4 - 1/2
b = -8/2 - 1/2
b = -9/2 <= this is the y-intercept
b is the y-intercept in slope-intercept form
Substitute b= -9/2 and m=1/4 to get the equation of the line.
y = 1/4 x - 9/2
Substitute y for 0 to find the x intercept
y = 1/4 x - 9/2
0 = 1/4 x - 9/2
9/2 = 1/4 x
x = (9/2) / (1/4)
x = (9/2) X (4/1)
x = 36/2
x = 18
A rational number is a number that can be made by dividing two integers. An integer is a number that doesn't have a fraction part.
1. 2.4 - rational
2. 74 - rational
3. 17.3333333… - rational
4. π -irrational
5. there is no number
6. –18 - rational
7. there is no number
8. 87.125 - rational
9. –30 - rational
10. –8.3 -rational
11. 58.25 -rational
12. 121 -rational
13. 4.5 -rational
14. 3 7/10 -rational
As you can see, most numbers are rational. But, when you come across pi or when you have a decimal that goes on forever without repeating (like some square roots), it tends to be irrational.
Answer:range is -2
Step-by-step explanation:
The answer to this question would be:
<span>Lower at 39 °F
The kinetic energy of a molecule is influenced by temperature. Higher temperature will result in higher kinetic energy which means the molecule moves at a higher velocity. This will increase the chance of the chemical reaction. That is why the rate of reaction will be higher at the higher temperature. Then, a lower temperature will mean a lower speed too.</span>
Step-by-step explanation:
To find the equation of the line in slope intercept form, we must have the slope and the y intercept. Finding the slope is easy:
So now we want the y intercept. We can use either points to do this, so for simplicity let's use the second one since the numbers are smaller. First of all, we have:
y=-3x+b. Plugging in 6 for x and 2 for y we have, 2=-18+b which means b=20. Checking our answer we have:
y=-3x+20 which means 8=-3*4+20, which is true. So our equation is indeed y=-3x+20
