The slope is equal to -4.
Hope this helps!
Answer:
Not sure what number 1 is but number 2 is true.
Step-by-step explanation:
In the equation x is the feet of width.
If the original width is 2 feet, then X^2 = 2^2 = 4
If the width changes to 4 feet, then x^2 becomes 4^2 = 16
The change is 16 - 4 = 12
The answer should be B. $12 per foot.
The answer is y = 2x + 0 or y = 2x.
The line passes through (0,0) and (1,2). The slope is
m = (2 − 0)/(1 − 0) = 2.
(You could also see this by drawing the two points and a slope triangle and use the rise/run idea of slope.)
In the slope-intercept form, y = mx + b, you now know that m = 2 and b = 0, so the answer is
y = 2x + 0 or y = 2x.
