4. What is the system of equations that describes the following graph?
GarryVolchara [31]

Answer:

The system of inequalities is

y

y>0.25x

Step-by-step explanation:

step 1

Find the equation of the dashed line with negative slope

The line passes through the points

(0,-2) and (-2,0)

Find the slope

m=(0+2)/(-2-0)=-1

Find the equation of the line in slope intercept form

y=mx+b

we have

m=-1\\b=-2

substitute

y=-x-2

The solution of the inequality is the shaded area below the dashed line

therefore

The equation of the inequality A is

y

step 2

Find the equation of the dashed line with positive slope

The line passes through the points

(0,0) and (4,1)

Find the slope

m=(1-0)/(4-0)=0.25

Find the equation of the line (direct variation)

y=kx

we have

k=0.25

substitute

y=0.25x

The solution of the inequality is the shaded area above the dashed line

therefore

The equation of the inequality B is

y>0.25x

therefore

The system of inequalities is

y

y>0.25x
