Answer:
y = -2x + -3
Step-by-step explanation:
The line has a slope of -2 because when counting from point to point, its 2 down and one over; 2/1 or 2 (negative because the line is going down)
The intercept in -3 because thats the first place the line touches the y axis.
The three ways are substitution, elimination, and graphing
Answer:
y=2
Step-by-step explanation:
<u>note:</u><u> </u><u>it</u><u> </u><u>only</u><u> </u><u>says</u><u> </u><u>to</u><u> </u><u>figure</u><u> </u><u>out</u><u> </u><u>y</u>
x+y+z=4
x+z+y=4
2+y=4 (since x+z=2)
y=4-2
y=2
