The slope wouldn't change, but the y-intercept would become 3 because you add -3 to 6

What is the area of a triangle that has a

almond37 [142]

Answer:

A. 45 in

Step-by-step explanation:

To find area you multiply length and width so you would multiply 9 and 10 but since it is a triangle you would divide by two

Hope this helps!

Solve. 2(2z – 4) = 4

Oxana [17]

Answer:

$z = 3$

Step-by-step explanation:

1) Divide both sides by 2.

$2z - 4 = \frac{4}{2}$

2) Simplify 4/2 to 2.

$2z - 4 = 2$

3) Add 4 to both sides.

$2z = 2 + 4$

4) Simplify 2 + 4 to 6.

$2z = 6$

5) Divide both sides by 2.

$z = \frac{6}{2}$

6) Simplify 6/2 to 3.

$z = 3$

therefor, the answer is z = 3.

Which ordered pairs could be points on a line parallel to the line that contains (3, 4) and (–2, 2)? Check all that apply.

Aleksandr-060686 [28]

Answer:

Step-by-step explanation:

As we go from (–2, 2) to (3, 4), x increases by 5 and y increases by 4. Thus, the slope of the line through (–2, 2) and (3, 4) is

m = rise / run = 4/5.

Use the slope-intercept form of the equation of a straight line:

y = mx + b becomes 4 = (4/5)(3) + b. Multiplying all three terms by 5, we eliminate the fraction: 20 = 12 + b. Thus, b = 8, and the equation of the line through (–2, 2) and (3, 4) is y = (4/5)x + 8.

A line parallel to this one would have the form y = (4/5)x + b; note that the slopes of these two lines are the same, but the y-intercept, b, would be different if the two lines do not coincide.

Unfortunately, you have not shared the ordered pairs given in this problem statement.

You could arbitrarily let b = 0. Then the parallel line has equation

y = (4/5)x; if x = 3, then y = (4/5)(3) = 12/5, and so (3, 12/5) lies on the parallel line.
