Question

graph the equation and identify the y-concept y+5y=15 where do both points go?

Answer 1

both points? you mean y intercept and x intercept? assuming you meant "x + 5y = 15", you find the y intercept by setting x=0 and solving for y:
0 + 5y = 15
y = 3
you find the x intercept by setting y=0 and solving for x.
x + 0 = 15
x = 15

So the two points are (0,3) and (15,0).

Answer 2

here's the graph with the points: http://bit.ly/puP2iY

Answer 3

so what is the y-intercept?

Answer 4

it's the point where the graph crosses the y axis.
