Answer:

In order to graph the line, you need to first find the y-intercept (aka 'b').

Equation: y=mx+b

Given the two points and slope, we can plug in and find for b

5 = 1/5(-2) + b

5 = -2/5 + b

b = 5 + 2/5

b = 27/5 or 5.4

So your final equation will be: y=1/5x+27/5

Lastly you just need to plot the 'b = 5.4' on the y-axis and place the slope as 1 over 5.

Hello there! :)

Given:

x-coordinate of point = -2

y-coordinate of point = 5

Slope, or "m" = 1/5

Substitute in these values into slope-intercept formula (y = mx+b)

5 = 1/5(-2) + b

5 = -2/5 + b

25/5 = -2/5 + b

27/5 = b

Rewrite the equation:

y = 1/5x + 27/5

Graph the equation using a graphing utility:

Alan just got a Fall job. The equation P = 12.50h represents the salary P (in dollars) he will earn when he works h hours. How m

balandron [24]

Given:

Alan salary P (in dollars) when he works h hours is represented by the equation

$P=12.50h$

To find:

The earning per hour.

Solution:

We have,

$P=12.50h$

Here, P is total salary and h is number of hours he works.

$\text{Earning per hour}= \dfrac{\text{Total salary}}{\text{Number of hours}}$

$\text{Earning per hour}= \dfrac{12.50h}{h}$

$\text{Earning per hour}=12.50$

Therefore, the earning per hour is $12.50.

Pls answer fast, i need to go to friends but parents wont let me.

Tanya [424]

Answer:

line C

Step-by-step explanation:

The equation would be

y= 1/2x

So that means the slope is 1/2

Starting at (0,0) we would go up 1 and over 2

That would be point (1,2)

That is the purple line, line C
