Find the slope and y-intercept of the line. 12x + 2y = –60

Mathematics
1 answer:

8 0

Answer:

<h2>slope = -6, y-intercept = -30</h2>

Step-by-step explanation:

The slope-intercept form of an equation of a line:

<em>y = mx + b</em>

<em>m</em><em> - slope</em>

<em>b</em><em> - y-intercept</em>

<em />

We have the equation in a standard form (<em>Ax + By = C</em>).

Convert to the slope-intercept form:

<em>12x + 2y = -60</em><em>                  subtract </em><em>12x</em><em> from both sides</em>

<em>12x - 12x + 2y = -12x - 60</em><em> </em>

<em>2y = -12x - 60</em><em>          divide both sides by 2</em>

<em>2y/2 = -12x/2 - 60/2</em>

<em>y = -6x - 30 → m = -6, b = -30</em>

8 books cost \$19.60$19.60dollar sign, 19, point, 60.
snow_tiger [21]

Answer: C=[ (10) x (19.60)÷ (8)]

Step-by-step explanation:

Given , The cost of 8 books = $ 19.60

Then, By UNITARY method , the cost of one book = ( Cost of 8 books ) ÷ ( 8)

i.e. The cost of one book = ($19.60) ÷ ( 8) ...(i)

Now , cost of 10 books = (10) x (Cost of one book)

From (i) , we get

Cost of 10 books =$[ (10) x (19.60)÷ (8)]

Let C be the cost of 10 books ( in dollars) .

So , the equation would help determine the cost of 10 :

C=[ (10) x (19.60)÷ (8)]
