How can the associative, commutative, and additive inverse properties be useful when adding and subtracting rational numbers?

1 answer:

7 0

Associative and commutative can move terms that are easy to combine and then add them. The additive inverse property helps you combine terms that are opposite to get 0

Graph the line passing through (6, 1) whose slope is m = 3.

Marina CMI [18]

Answer: $y=3x-17$

Step-by-step explanation:

use point-slope form:

$y_{1} -y=m(x_{1} -x)$

$y-1=3(x-6)$

$y-1=3x-18$

$y=3x-17$

Which system of equations can be used to solve for the point of intersection of the lines on the graph? A) y = x - 7; y = 2x + 2

ratelena [41]

Answer:

C) y = 2x + 7; y = 2x + 2

Step-by-step explanation:

The two lines are parallel and so will have the same slope.

From the graph, the slope of both lines are two.

Using slope intercept formula, y=mx+c, with m=2, we have y=2x+c

The blue line has a y-intercept of 2 so the equation is

$y = 2x + 2$

The red line has a y-intercept of -7 so the equation is

$y = 2x - 7$

Hence the system is

y=2x+2

y=2x-7

The correct answer is C
