I NEED MORE HELP THIS IS DIFFICULT:(

A. The slope is 7/2, The y-intercept is (0,-3)

Step-by-step explanation:

The slope of a line passing through two points P=(x1,y1) and Q=(x2,y2) is given by m=y2−y1x2−x1.

We have that x1=0, y1=−3, x2=2, and y2=4.

Plug the given values into the formula for a slope: m=4−(−3)/2−0=72.

Now, the y-intercept is b=y1−mx1 (or b=y2−mx2, the result is the same).

b = -3 - (7/2) × (0) = -3

Finally, the equation of the line can be written in the form y=b+mx:

y = 7/2x - 3

answer: i think it is (1,-2)

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
