Answer:

The slope of the line is 5

Step-by-step explanation:

When we talk of the slope of a straight line graph, we refer to the rate at which the values on the y-axis changes as a ratio of the changes we have on the x-axis

Now, from the question, number of hours is placed on x-axis, while we have the amounts on the y-axis

having $5 per hour means the rate of change of what is earned to number of hours worked is 5 and this is the slope of the line

Answer:

1/2

Step-by-step explanation:

We do change in y over change in x

Formula for Rate of Change on Slope

y2-y1/x2-x1

For Y

We use coordinate (-2, -4)

-4--2

= -2 - -4

= 2

For X

We use coordinate (0, -4)

0 -- 4

= 0 + 4

= 4

Now we put y over x to find the rate of change in slope

2/4, simplified would be 1/2

Answer:

(4,-2)

Step-by-step explanation:

If we are reflecting a point across the y-axis, that point must be on the same horizontal line that the pre-mage is was, this means the y coordinate must remain the same. Now we want the points on both sides of the y-axis to have the same distance. x and -x have the same distance from 0. This means you will need to take the opposite of x.

So a point (x,y) being reflected over the y-axis will give (-x,y).

( x , y)->(-x,y) means we have:

(-4,-2 )->(4,-2)

You can graph this to confirm it looks like a reflection through the y-axis.

Find the equation of the line that is perpendicular to LaTeX: y=-\frac{1}{5}x+3y = − 1 5 x + 3 and goes through the point (4, -3

Elenna [48]

Answer:

$y=5x-23$

Step-by-step explanation:

step 1

Find the slope of the line that is perpendicular to the given line

we have

$y=-\frac{1}{5}x+3$ -----> given line

The slope of the given line is

$m=-\frac{1}{5}$

Remember that

If two lines are perpendicular, then their slopes are opposite reciprocal

therefore

The slope of the line that is perpendicular to the given line is

$m=5$

step 2

Find the equation of the line in slope intercept form

$y=mx+b$

we have

$m=5\\point\ (4,-3)$

substitute

$-3=5(4)+b$

solve for b

$b=-23$

therefore

$y=5x-23$

Your class wants to know to most typical age of student in your class. It collects the ages of all students and the teacher. Whi

dem82 [27]

Answer:

Median.

Step-by-step explanation:

Assuming the teacher is not of similar age to the students, their higher age would pull the mean higher than if the teacher were not included, where the median would not be pulled by this extreme value.

What is the x-intercept of the line with this equation −2r+1/2 y=18?

Anon25 [30]

To find the x int, we will sub in 0 for y and solve for x...um...r

- 2r + 1/2y = 18
-2r + 1/2(0) = 18
-2r = 18
r = -18/2
r = -9

so the x int is (-9,0)
