The answer would be B and D. This can be found by putting the x and y values into the inequality to find whether or not they are true.
The answer is 12 good luck;)
Look for the y-intercept
since we know the slope is 3 we just going to plug in
-5=3(1)+y
-5-3=y
so the y-intercept is 8 now you can find the equation
y=3x-8
The width of the laptop is 6 inches long.
X-intercept: (7,0)
y-intercept: (0,2)
