Help!!!!!! <br><br>complete the problem involving the linear equation. ​
Arisa [49]

Answer:

<h2>8. slope = 2</h2><h2>9. y-intercept = -3</h2><h2>10. in the attachment</h2>

Step-by-step explanation:

The slope-intercept form y = mx + b

m - slope

b - y-intercept → (0, b)

We have the equation

y - 2x = -3              <em>add 2x to both sides</em>

y = 2x - 3

slope m = 2

y-intercept b = -3

We need two points to draw a graph of this linear function.

One is y-intercept (0, -3). The second one is calculated by choosing any value of x and put it to the equation:

for x = 2 → y = 2(2) - 3 = 4 - 3 = 1 → (2, 1).

Marc saved 30% of his monthly salary each month. His monthly salary in December was $ 3650. In January, his salary increased by
DiKsa [7]

Marc saved $2,533  in January than in December.

Step by Step calculation.

Given the details below :

Salary In December =$3,650

In January, Increased by 12%

Marc saves 30% of $3,650 in December

New salary can then be calculated as :

= Initial salary * % increase / 100 + Initial salary

= 3,650 * 12 / 100 + 3,650

= 3,650 * 0.12 + 3,650

= 4,088

The difference will now be

= 4,088 - 3650

= $438

Since Marc saves in December 30% of $3,650

= 30% of $3,650

= $1,095

Saves in January

= 1,095 + 438

= $2,533
