Answer:
For any two given points (x1,y1) and (x2,y2), the slope = (y2-y1)/(x2-x1)
Let's take the points (15,3) and (30, 6):
slope = (y2-y1)/(x2-x1)
= (6-3)/(30-15)
=3/15
=1/5 =0.2
The slope, in general, means the rate of change of y, relative to x. In the context of this question, the slope tells us that the amount of concrete that can be poured (in yards) is a fifth of the time taken (in minutes).
X-intercept means y equals to 0
y-intercept means x equals to 0
If you plug in (0, 1) and (1, 0), you will notice that only x + y = 1 will work for both points
Your answer is B) x + y = 1
Answer:
-5/12
Step-by-step explanation:
Solve for x by simplifying both sides of the equation, then isolating the variable.
Answer:
73/5
Step-by-step explanation:
Answer:
the answer is y=8.5x
Step-by-step explanation:
because x would equal the hours and y would equal the money.
so you divide y by x, so in this case it would be 127.50/15 and that equals 8.5
so the multiplier or constant of proportionality, if thats what you guys call it, is 8.5.
