Question

4x+5y=20

Answer 1

y=4-(4/5)x

Answer 2

want more than the answer?

Answer 3

yes

Answer 4

are you doing graphs in algebra? slope, y-intercept, that kind of thing?

Answer 5

yes im graphing a line of y =intercept

Answer 6

ok
4x+5y=20 and we want y as a function of x, so solve for y:
-4x -4x
----------
5y=20-4x=-4x+20
divide both sides by 5:
y=-(4/5)x+20/5=(-4/5)x+4=mx+b
where b is the y-int
so they want you to graph
y=4
since that doesn't depend on x, y=4 everywhere; it's a horizontal line at y=4, so that's what you graph.

Answer 7

write an equation of a line
slope 6;through (0,4)
