Just take the coordinates of both those red dots and use the slope formula: y2-y1 all divided by x2-x1. that should give you slope

The formula to find the slope of a line is\frac{y_{2}-y_{1}}{x_{2}-x_{1}}, in other words <em>the y coordinate of the second point minus the y coordinate of the first point over the x coordinate of the second point minus the x coordinate of the first point</em>.  


On this graph, the two points given are (-3,4) and (1,-2).  With this, we can determine x_{1} , x_{2} , y_{1} , and y_{2}

x_{1}=-3 \\ x_{2}=1\\ y_{1}=4\\ y_{2}=-2


Plug these values correctly into the slope formula, and you can find your answer.

\frac{-2-4}{1--3} =\frac{-6}{4} =\frac{-3}{2}


The slope of the line is-3/2.


Hope this helps!

Liam is saving up for a new cell phone. He uses the equation P= I + HB, where P is the cost
Stels [109]

Answer:

H=\dfrac{P-I}{B}

Step-by-step explanation:

Given the expression: P= I + HB

Where:

  • P = cost  of the phone Liam is saving for.
  • I = amount of money he started with.
  • H = number of hours he  babysits
  • B = hourly rate for babysitting.

We want to find an expression for H, the number  of hours Liam will need to babysit to save enough money for a cell phone.

Our goal is to isolate the variable H in the expression P= I + HB.

P= I + HB

Subtract I from both sides

P-I=I-I+HB

HB=P-I

Divide both sides by B

\dfrac{HB}{B} =\dfrac{P-I}{B}\\\\$Therefore\\\\H=\dfrac{P-I}{B}

Solve for z -0.25z= -1.25
GarryVolchara [31]

Answer:

<h2>z = 5</h2>

Step-by-step explanation:

-0.25z= -1.25

Convert the decimals to improper fractions

That's

<h3>- 1.25 =  -  \frac{5}{4}</h3><h3>- 0.25 =  -  \frac{1}{4}</h3>

So we have

<h3>-  \frac{1}{4} z =  -  \frac{5}{4}</h3>

Multiply through by 4

We have

- z = - 5

Divide both sides by - 1

the final answer is

<h3>z = 5</h3>

Hope this helps you
