Answer:
Step-by-step explanation:
y=-1 is a horizontal line going through y=-1. x=-1 is a vertical line going through x=-1.
y=-1 has a slope of zero. the y-intercept is -1.
x=-1 has no slope. the slope is undefined. there is no y-intercept.
The diagonal line is equal to
using pythagoras' theorem of
. This gives us a value of 51m for the diagonal line.

Answer:
B.) 80 cans, 20 brushes
Step-by-step explanation:
Let the cans of paint be represented by variable <em>p</em> , and brushes by variable <em>b</em>
The first equation would be ; p + b = 100
p = 100 - b
The second equation would be;
8p + 12b = 880
Replace p in the equation by (100-b);
=8(100-b) + 12b =880
=800 - 8b +12b = 880
= subtract 800 from both sides to get;
4b = 880-800
4b = 80
divide both sides by 4 to solve for b;
b= 80/4
b = 20
If p + b = 100, then p+20 = 100
p = 100-20
p = 80
Therefore, they sold 80 cans of paint and 20 brushes
