Which of the lines graphed has a slope of 1 and a y-intercept of -3?

C

Step-by-step explanation:

The line has a positive slope which means it slopes upwards from left to right

A and B  slope downwards so can be excluded

C and D have the correct upward slope but C has the y-intercept of - 3

Thus C is the required line

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
