What is the equation of the line passing through the points (2, -1) and (5.-10) in slope-intercept form

Answer:

y = -3x + 5

Step-by-step explanation:

Usually by drawing a simple graph, you can tell what the equation is, even if the graph isn't 100% accurate. From the points alone, you can tell that the slope is negative, since as you increase in x you decrease in y (which is a negative relationship). You can tell that it's +5 rather than -5 because the graph sketched shows that the line goes above 0 (indicating a positive number), rather than below (a negative number).

Xavier and Ava are employees for a company. Xavier is making a salary of $42,700.
MrMuchimi

$62,342 is the salary earned by Ava.

<u>Step-by-step explanation</u>:

<u>step 1</u> :

Xavier's salary = $42,700

<u>step 2</u> :

Ava's salary = 46% higher than Xavier salary.

                    = 100% of Xavier salary + 46% of Xavier salary

                    = 146% of Xavier salary

<u>step 3 </u>:

Ava is earning a salary = (146/100)\times42,700

                                      = 146 \times 427

                                      = 62,342

∴ Ava is earning a salary of $62,342.

How to do an equation like this step by step? 4.5 (8 - x) + 36 = 100 - 2.5 (3x + 24)
Levart [38]

Answer:

x = -10.6667

Step-by-step explanation:

Solve for x:

4.5 (8 - x) + 36 = 100 - 2.5 (3 x + 24)

4.5 (8 - x) = 36 - 4.5 x:

36 - 4.5 x + 36 = 100 - 2.5 (3 x + 24)

Grouping like terms, -4.5 x + 36 + 36 = (36 + 36) - 4.5 x:

(36 + 36) - 4.5 x = 100 - 2.5 (3 x + 24)

36 + 36 = 72:

72 - 4.5 x = 100 - 2.5 (3 x + 24)

-2.5 (3 x + 24) = -7.5 x - 60:

72 - 4.5 x = -7.5 x - 60 + 100

Grouping like terms, -7.5 x - 60 + 100 = (100 - 60) - 7.5 x:

72 - 4.5 x = (100 - 60) - 7.5 x

100 - 60 = 40:

72 - 4.5 x = 40 - 7.5 x

Add 7.5 x to both sides:

7.5 x - 4.5 x + 72 = (7.5 x - 7.5 x) + 40

7.5 x - 7.5 x = 0:

7.5 x - 4.5 x + 72 = 40

Grouping like terms, 7.5 x - 4.5 x + 72 = (-4.5 x + 7.5 x) + 72:

(-4.5 x + 7.5 x) + 72 = 40

7.5 x - 4.5 x = 3 x:

3 x + 72 = 40

Subtract 72 from both sides:

3 x + (72 - 72) = 40 - 72

72 - 72 = 0:

3 x = 40 - 72

40 - 72 = -32:

3 x = -32

Divide both sides of 3 x = -32 by 3:

(3 x)/3 = (-32)/3

3/3 = 1:

x = (-32)/3

(-32)/3 = -10.6667:

Answer: x = -10.6667

If two points on line l above have coordinates (0, A) and (2, −3), and the slope of the line is A, then what is the value of A?
Anna35 [415]

<u>ANSWER: </u>

If two points on line l above have coordinates (0, A) and (2, −3), then the value of A is -1

<u>SOLUTION:</u>

Given, two points on line l have coordinates (0, A) and (2, −3),

And the slope of the line is A,

We need to find a value.

We know that, slope of a line on which (x1, y1) and (x2, y2) are two points is given by

\mathrm{m}=\frac{y_{2}-y_{1}}{\mathrm{x}_{2}-\mathrm{x}_{1}}

Here,in our problem,

\mathrm{m}=\mathrm{A}, \mathrm{x}_{2}=2, \mathrm{x}_{1}=0, \mathrm{y}_{2}=-3 \text { and } \mathrm{y}_{1}=\mathrm{A}

now, substitute the values in formula we get

\begin{array}{l}{A=\frac{-3-A}{2-0}} \\\\ {A=\frac{-3-A}{2}}\end{array}

2A = -3 –A

2A+ A = -3

3A = -3

A = -1

Hence, the value of A is -1.
