Where does -3x - 5y = 35 cross the y axis?

Question

i have to kno this for skool, gosh, hate it...

Answer 1

linear equations always have to be converted to the form

Y=mX + b

m is the slope

b is the y intercept

So, lets change your equation into the correct form by isolating the Y

-3X-5Y=35

move the -3X

-5Y= 3X+35

divide by 5

-Y= 3/5X + 7

multiply the whole equation by -1

Y= -3/5X-7

That means the slope is -3/5

and the Y intercept is -7

Answer 2

-3x - 5y=35

+3x          +3x  (add 3x to both sides of the equation)

-5y=3x + 35

___ __    ___ (now divide each part by -5)

-5      -5      -5  (the 5s are supposed to be lined up under thelines)

leaving you with....

y=3/5x + -7    (this is tells you the slope of the line is 3/5 and the y-intercept is at -7)

Answer 3

The line crosses the Y axis where x=0

so -5y = 35

-y = 7

y = -7
