express the following questions in slope intercept form:5x+8y=40

Question

kc_kennylau · Answer

That's the same as putting y as the subject :)

kc_kennylau · Answer

5x+8y=40
8y=40-5x
y=-5/8x+40/8
y=-0.625x+5

anonymous · Answer

slope intercept form is y=mx+b

kc_kennylau · Answer

m=-0.625
b=5

    y=mx+b
    y is the answer so it stays y.
    m is the slope
    x is the x intercept ehich stays x
    b is the y intercept
    so the form you see it in now is ax+by=c
    so to solve for y subtract ax on both sides
    then divide by whatever to make by equal to one sometimes no need to divide.
    here is an example 6x+5y=-30
    subtrract 6x from both sides
    5y=-6x-30
    divide by negative five
    y=6/5x+6
    hope that helped i love algebra!!:)
