Graph the line with slope -1/2 passing through the point (-1,-2)

Mathematics
1 answer:
Bezzdna [24]3 years ago
6 0

Answer:

See attachment for graph

Step-by-step explanation:

Given

m = -\frac{1}{2}

(x_1,y_1) = (-1,2)

Required

Graph the line

First, is to determine the equation of the line using:

m = \frac{y - y_1}{x - x_1}

So:

-\frac{1}{2} = \frac{y - 2}{x - -1}

-\frac{1}{2} = \frac{y - 2}{x +1}

\frac{-1}{2} = \frac{y - 2}{x +1}

Cross multiply:

(y -2) * 2 = -1 * (x + 1)

(y -2) * 2 = -x -1

Solve for y - 2

y -2 = -\frac{x}{2} -\frac{1}{2}

Solve for y

y  = -\frac{x}{2} -\frac{1}{2} + 2

y  = -\frac{x}{2} +\frac{-1+4}{2}

y  = -\frac{x}{2} +\frac{3}{2}

<em>The above equation will then be plotted on the graph (See attachment)</em>

3,000. You take 15,000 and multiply by .4 to get how much she spent on rent (6,000). They you subtract the rent money from her total pay to get her money that she spent on living expenses, clothes and entertainment in total (9,000). Since she spent her money in six parts (3+2+1), you divide 9,000 by 6 to get 1,500 to get each part. Since for entertainment she has two parts you multiply 1,500 by 2 to get 3,000.
