For this, you simply plug in 0 for "x" and solve:
2(0) - 3y = 12 multiply 2x0 to get 0
0 - 3y = 12 0 - 3y is -3y
-3y = 12 Isolate your variable by diving both sides by -3
y = -4 you're left with y = -4
Answer: if x is 0, y is -4
Hello!
So to find the y-coordinate we need an equation for the line. The equation we can use is
y = mx + b
In this we already know m(the slope which is 3) and we can find b by plugging in the points that are given.
10 = 3(0) + b
10 = 0 + b
10 = b
So now that we've found b, we can use this in our equation
y = 4x + b
So now we can plug in the x-coordinate that we know (2) and find the y - coordinate.
y = 4(2) + 10
y = 8 + 10
y = 18
18 is your y-coordinate
First add the number of total larges ordered 22+5=27 then divide 22/27=.814 to make the answer a percent times by 100. .814x100=81.5% to double check you can multiply .814 by number of larges and should get number of hot larges ordered. .814x27=22
