What is the slope of the line that passes through the points (3, -4) and (7, 4)?

1 answer:

6 0

The correct option is: Option (C) 2

Explanation:

The slope formula is = m = $\frac{y_2 - y_1}{x_2 - x_1}$

Insert the values in the above formula:

m = $\frac{4 - (-4)}{7 - 3} = \frac{8}{4} = 2$

Which is Option (C).

Answer:

reflected over the x-axis, compressed horizontally by a factor of 1/2.

Step-by-step explanation:

y(x) and f(x) means the same.

y = -(2x) means that y(x) was multiplied by -1, and x was replaced by 2x

-y(x) reflects y(x) across x-axis

y(a*x) compresses horizontally y(x) by a factor of 1/a. Here, a is 2, then the factor is 1/2.

Can someone please help me with this

Alex_Xolod [135]

Answer:

135°

Step-by-step explanation:

The reference angle appears to be about 45°, so a reasonable estimate of the angle size is 180° -45° = 135°.

You can do an eyeball comparison with the figure attached to see that the angle is about 135°

This is also the value I see when I place my protractor against the screen.

Hi!

<u>Given these two equations:</u>

$x = y + 8$

$x + 4 = 2(y + 4)$

We want to solve using the substitution method. Knowing that x is equal to y + 8, we can simply plug in 'y + 8' in for x in the second equation, like so:

$(y+8)+4=2(y+4)$
