-- If two lines on a graph are parallel, then their slopes are equal.
-- If two lines on a graph are perpendicular, then their slopes are
negative reciprocals.
Answer:
D!!
Step-by-step explanation:
Using proportions, it is found that the coordinates of point B are given as follows:
A. (1.6, 0).
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
Point B is 3/4 of the way from AB to AC, hence:
The points are:
Then, to find the x-coordinate:
x + 2 = 3.6.
x = 1.6.
For the y-coordinate:
y + 3 = 3
y = 0.
Hence option A is correct.

Answer:
associative
combining
commutative
Step-by-step explanation:
1. <em>associative property of addition</em> since the grouping is changed
2. <em>combining like terms</em> since it's the addition of 4 and 6
3. <em>commutative property of addition</em> since it's a change of order
Answer:
Expressions for y:
1. A - 3B
3. A/3 - B
3. (27/13, -60/13)
Step-by-step explanation:
Expressions for y:
A - 3B
A/3 - B
Find combinations to eliminate x
A) 8x + y = 12
B) 2x - 3y = 18
Expressions for y:
A - 3B
A/3 - B
y = 12 - 8x
2x - 3(12 - 8x) = 18
2x + 24x - 36 = 18
26x = 54
x = 54/26 = 27/13
y = 12 - 8(27/13) = -60/13
