Answer:

y<\frac{-1}{3}x+1 is inequality shown on graph.

Step-by-step explanation:

The graph shows representation of inequality,

Here, Line passes through points say, A(3,0) and B(0,1)

The slope of line is given by m=\frac{Y2-Y1}{X2-X1}

m=\frac{Y2-Y1}{X2-X1}

m=\frac{1-0}{0-3}

m=\frac{-1}{3}

and Y-intercept is c=1

The equation of line is given by y=mx+c

y=\frac{-1}{3}x+1 is equation of line in graph.

To decide which side you are going to shaded area on the graph

Take test of origin.

If (0,0) is statisfy the equation then, shaded the graph towards the origin.

Let suppose,

Take, y<\frac{-1}{3}x+1

0<\frac{-1}{3}(0)+1

0<1

TRUE,

Therefore, y<\frac{-1}{3}x+1 is inequality shown on graph.

X - the number of questions he answered correctly
y - the number of questions he answered incorrectly

There were 40 questions on the test.
x+y=40 \\ y=40-x

The correct answers were given 5 points each, the incorrect answers were given -2 points each. He made a score of 95.
5x-2y=95 \\&#10;-2y=95-5x \\&#10;y=-\frac{95}{2}+\frac{5}{2}x&#10;

Set 40-x and (-95/2)+(5/2)x equal to each other:
40-x=-\frac{95}{2}+\frac{5}{2}x \\&#10;-x-\frac{5}{2}x=-\frac{95}{2}-40 \\&#10;-\frac{2}{2}x-\frac{5}{2}x=-\frac{95}{2}-\frac{80}{2} \\&#10;-\frac{7}{2}x=-\frac{175}{2} \\&#10;x=-\frac{175}{2} \times (-\frac{2}{7}) \\&#10;x=\frac{175}{7} \\&#10;x=25

Johnny answered correctly 25 questions.
