Answer:

Equations in slope-intercept form for three different lines that intersect at (–2, 3) are y=-x+1  ,  y=3  and y=x+5

Step-by-step explanation:

General equation of slope intercept form : y-y_1=m(x-x_1)

We are supposed to find equations in slope-intercept form for three different lines that intersect at (–2, 3).

(x_1,y_1)=(-2,3)

Substitute the value in the general equation

y-3=m(x+2)

Now substitute any 3 values of m

At m = -1

\Rightarrow y-3=-x-2 \\\Rightarrow y=-x+1

At m =0

\Rightarrow y-3=0 \\\Rightarrow y=3

At m =1

\Rightarrow y-3=x+2 \\\Rightarrow y=x+5

They all intersect at the given point.

So, equations in slope-intercept form for three different lines that intersect at (–2, 3) are y=-x+1  ,  y=3  and y=x+5

NARA [144]

so to find 15% of 54,237, we use this equation: (x/54237) = (15/100) where x is the amount of income tax.

cross multiply: 100x = 813555

divide each side by 100 to isolate x: 8135.55

What is an equation of the line that passes through the points (-4,1) and (4,4)?
Ray Of Light [21]

Answer:

y = \frac{3}{8} x +  \frac{5}{2}

Step-by-step explanation:

☆Remember: m =  \frac{y_2 - y_1}{x_2 - x_1}

☆Remember: Slope-intercept form -> y = mx + b

☆Now. We first need to find the slope.

m =  \frac{4 - 1}{4 -  (- 4)}  =  \frac{3}{8}

☆Now the y-intercept.

y =  mx + b \\  \\ 4 =  \frac{3}{8} (4) + b \\  \\ 4 =  \frac{3}{2}  + b \\   \frac{ -  \frac{ 3}{  2} =  -  \frac{ 3}{ 2}  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  }{ \frac{5}{2} = b }

Tell whether each graph is a function and justify your answer. Which graph is not a good representation of a​ real-world situati
mina [271]

Using the function concept, it is found that:

  • Graph B is a function because each value of x corresponds to exactly one y-value.

In a function, <u>one value of the input can be related to only one value of the output</u>.

  • In a graph, it means that for each value of x(horizontal axis), there can be only one respective value of y(vertical axis).

In this problem, at Graph A, when x = 5, for example a vertical line crosses the function 3 times, hence there are 3 respective values of y for x = 5, and the same is valid for other values of x, hence it is not a function.

At Graph B, <u>for each value of x, there is only one value of y</u>, hence it is a function.

Hence:

Graph B is a function because each value of x corresponds to exactly one y-value.

Can a linear equation and a linear inequality be solved in the same way
frez [133]
You can solve them in the same way. you can add any positive or negative number to both the sides of an inequality.Also you can multiply  or divide both sides of an inequality by any positive number hope this helps.   :)
