How do you write equation for rise ove run
SashulF [63]
Y = mx + b

M= your slope or rise over run

B = your y-intercept

For example if the rise was 5 and the run is 6, the equation would say
y = 5/6 + b
The / being your fraction bar

The y-intercept is where your line crosses the y-axis
So say that the line crosses the y-axis at 10
y = 5/6 + 10

That about sums it all up!

Choose all pairs of points that are reflections of each other across both axes. A. (–412, 1) and (–1, 412) B. (2.5, –1) and (–21
SVEN [57.7K]

Answer:

The correct option is;

(-2, 213) and (2, -213)

Step-by-step explanation:

The reflection of a point across the x-axis is given as follows;

The coordinates of the point of the pre-image = (x, y)

The coordinates of the point of the image after reflection = (x, -y)

The reflection of a point across the y-axis is given as follows;

The coordinates of the point of the pre-image = (x, y)

The coordinates of the point of the image after reflection = (-x, y)

Therefore, from the given points, The reflection across the y-axis of the point (-2, 213) is (2, 213) and the reflection across the x-axis of the point (2, 213) is (2, -213)

Alexa worked 30 hours last week and earned $450. Her pay has now been increased by 20%. Which equation describes her new rate of
vesna_86 [32]

Answer:

p=18h

or

p=\dfrac{450}{30}\cdot 1.2\cdot h

Step-by-step explanation:

If Alexa worked 30 hours last week and earned $450, then her hourly payment is

\dfrac{\$450}{30}=\$15.

Her payment has now been increased by 20%, so her hourly payment becomes

\$15\cdot 1.2=\$18.

If she worked h hours, then she earned \$18h. If her new payment is p, then

p=18h

or

p=\dfrac{450}{30}\cdot 1.2\cdot h.

Musya8 [376]
4th answer because the ratios are not the same. The ratios need to be the same. 1:2 and 2:4 ratio is the same because the fraction 1/2 is the same as 2/4. So, 3:4 ratio is the same as 9:12 because 3/4 is the same as 9/12. However 7:4 ratio or 7/4 is not the same as 4/3. So they are not similar.
