Answer:
the slope is change in the independent variable divided by the change in the dependent variable. in this case 800-400/5-1 = 100
Step-by-step explanation:
change in independent variable = 800 - 400
change in dependent variable = 5 - 1 = 4
divide the change = 400/4 = 100.
Note, this can work with any values you use in the table and your answer remains constant
You kneed to find the slope of the line to make one parallel to it. you can do so by using the 2 coordinates they gave you: (-4, 0) and (4, -4).
Slope is change in y divided by the change in x.
The 'Y' changed from 0 to -4, so it went down 4.
The 'X' changed from -4 to +4, so it went up 8.
(-4)/(8) is -1/2.
You can put this into the slope-intercept formula (y = mx + b) to get y = -1/2x + b. This is not the full equation, however. To get there, insert the point that the new line needs to go through into this formula and solve for b.
The point is (2, 3), so x = 2 and y = 3.
(3) = -1/2(2) + b
3 = - 1 + b
+1 +1
4 = b
This means that the equation you need is y = -1/2(x) + 4
Answer:
4. 16.5
Step-by-step explanation:
You solve for the hypotenuse
a^2+b^2=c^2
16^2+4^2=c^2
256+16= the square root of 272
16.5
