Answer:
Step-by-step explanation:
The slope intercept form of a line is y=mx+b where m is the slope and b is the y intercept. We are given a slope of three so
y=3x+b, using point (1,3) we can solve for b
3=3(1)+b, 3-3=0 so b=0 then our line is
y=3x
The x intercept is when y=0 and this occurs when x=0 or the point (0,0)
The y intercept occurs when x=0, this occurs when y=0 or the point (0,0)
Answer: Communitive property of addition
Step-by-step explanation:
The communitive property states that if you reverse the order of a multiplication or addition problem you will get the same result.

Answer:
B -3.
Step-by-step explanation:
The slope = (y2-y1)/(x2-x1)
= (-2-4)/(8-6)
= -6/2
= -3.
Answer:
C) a positive correlation
Step-by-step explanation:
<em>More people ⇒ Longer time</em> is a positive correlation between those variables. However, <em>longer time</em> is not the desired outcome.
Rather, <em>shorter time</em> is the desired outcome. The correlation between <em>more people</em> and <em>shorter time</em> is negative. In order to compute that correlation numerically, one would have to define a function that would give a numerical value for "shorter time" that would model the goodness of outcome as time gets shorter.
