Step-by-step explanation:
Not sire if i'm correct but, I'm pretty sure it's widthxlength.
Find your x and y intercepts. Once you have those 2 points you can connect them. Use a test point, a point that is not on the line to see what side you're shading. If your test point proves that the equation is false, you shade away from your line. If it's true to shade towards your line.
Okay so what you would do is 1.5 multiply by 3 find out the answer there and then subtract the 5 cups with the answer.
so if it is 1.5×3 that would equal ____ then you would subract 5 - ___ then there is your answer
Plug in -3 for x
f(-3) = 2(-3) - (-3 + 6)
f(-3) = -6 - (3)
f(-3) = -9
Solution: f(-3) = -9
