Use the graph to answer the exercises 36 and 37

Answer 36:

y>(-1)x+2

Answer 37:

The point of intersection is (,)

Step-by-step explanation:

Given graph show shaded area of inequality

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

where m is the slope of line and c is y-intercept of a line

The slope is given by m=

For the red line:

Here, Redline is passing through the point (2,0) and (0,2)

The slope of the red line will be

m=

m=

m=(-1)

and y-intercept of the line is c=2

The equation of the red line is given by

y=mx+c

y=(-1)x+2

To find which inequality holds true for the red line

Let inequality for red line be y>(-1)x+2

Now,

Take a random point from the shaded section of the graph

Let that point be (2,1)

Test that point,

y>(-1)x+2

1>(-1)2+2

1>0

True, The required inequality for a red line is y>(-1)x+2

For the blue line:

Here,blue line is passing through the point (0,0) and (1,4)

The slope of the red line will be

m=

m=

m=4

and y-intercept of the line is c=0

The equation of the blue line is given by

y=mx+c

y=4x

To find which inequality holds true for the blue line

Let inequality for blue line be

Now,

Take a random point from the shaded section of the graph

Let that point be (0,1)

Test that point,

True, The required inequality for a blue line is

Answer 36:

y>(-1)x+2

To find a point of intersection of system of the equation:

Equation 1: y=(-1)x+2

Equation 2: y=4x

Replacing value of y in the equation 1

we get

y=(-1)x+2

4x=(-1)x+2

5x=2

x=

y=4x=4

y=

Thus, The point of intersection is (,)

Answer 37:

The point of intersection is (,)

175

step-by-step explanation:

2 inches x 10 miles = 200 miles - 3 inches = 175

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2
