The first one is the correct answer :))
B:
Crossing the Y axis (y-intercept) means that the X value is zero. So, plug zero into the equation.
Y = 3(0)+1
Y =1
So the ordered pair for the Y intercept is (0,1)
For the X intercept, the Y value is equal to zero, so do the same thing except with Y
0 = 3(x) +1
-1 = 3x
x=-1/3
So the ordered pair is (-1/3,0)
E
Y intercept: (0,0)
X intercept (0,0)
First let's find out how many cups serve one person.
3 ÷ 5 = 1.6
1.6 of a cup serves one person.
1.6 × 13 = 20.8
It takes 20.8 (21 rounded) to serve 13 people.
Just substitute 5 into a and -2 into k
M+g≤40
12m+14g=x where x is his total earnings for the week
12m+12g+2g=x, so x-2g=12(m+g) and x-2g≤480. Or x≤480+2g. His earnings cannot exceed 480+2g.
