Answer:

slope is -4/3 and y-int is -1

Step-by-step explanation:

Solve for y

3y = -3 - 4x

y = -4x/3 - 1

so the slope is -4/3

the y intercept is -1

Start by making a point at (0,-1), then count 4 down and 3 to the right and make another point. Continue to do this until you have a line long enough.

20 days
x=number of days vacation
y=daily expenses
xy=1100
(x+2)(y-5)=1100
*******
xy-5x+2y-10=1100
xy-5x+2y=1110
y=1100/x
x(1100/x)-5x+2(1100/x)=1110
1100-5x+(2200/x)=1110
-5x+(2200/x)=10
-5x^2 + 2200 = 10x
-x^2 + (440) = 2x
x^2 - 440 + 2x = 0
(x+22)(x-20)=0
x=-22,20
only take the positive answer because the negative answer doesn't make sense in the question
so the answer is 20

I might be wrong; this question probation should've been this hard so I might have taken a wrong turn somewhere. feel free to double check my work
