Find the y-intercept.3x – y = –15?

Answer 1

let

x = 0

3x - y = - 15

3(0) - y = - 15

0 - y = - 15

- y = - 15

- 1(- y) = - 1(- 15)

- (- y) = - (- 15)

y = 15

The y intercept is 15

- - - - - - - -s-

Answer 2

The y intercept is the point on the y-axis where the line crosses. Since the y-axis lies along the line x=0 then all points on it must have x=0. So to find the y-intercept of any equation simply substitute x=0 and solve for y.

3x-y=-15

set x=0

3(0)-y=-15

-y=-15

y=15

or
Express the equation in the form x/a + y/b = 1.
Then x intercept is a and y intercept is b

In this equation by dividing both sides by -15 we get
x/(-5) + y/15 = 1

So y intercept is 15


Taking a practical approach to the problem, a y-intercept exists where X=0. So set X=0 in the equation and you'll get -Y == -15, or Y=15

the y-intercept is 15

Answer 3

The y intercept is the point on the y-axis where the line crosses. Since the y-axis lies along the line x=0 then all points on it must have x=0. So to find the y-intercept of any equation simply substitute x=0 and solve for y.

3x-y=-15

set x=0

3(0)-y=-15

-y=-15

y=15

Answer 4

Taking a practical approach to the problem, a y-intercept exists where X=0. So set X=0 in the equation and you'll get -Y == -15, or Y=15

Answer 5

Express the equation in the form x/a + y/b = 1.
Then x intercept is a and y intercept is b

In this equation by dividing both sides by -15 we get
x/(-5) + y/15 = 1

So y intercept is 15

Answer 6

3x - y = -15
At y - intercept, x = 0
3(0) - y = -15
y = 15

Answer 7

In a standard form equation: y=mx+b, the y intercept is represented by b.
Simply write this equation in standard form.
3x-y=-15
-y=-3x-15
y=3x+15
The y intercept is 15

Answer 8

Here we have to find the y-intercept of the given equation.
consider this equation.
y = mx +c , where c is known as y-intercept.
so what we need to do is, to convert the given equation as in the form of y = mx +c.
First subtract 3x from both sides,
-y = -15 -3x
Next multiply both sides by -1 to get y alone on the left side.
y = 15+3x
It's equivalent to,
y = 3x +15
so the y- intercept is 15. More generally (0,15).

Answer 9

the y-intercept is 15

to find the y-intercept, the x must be 0

so

3x - y = -15
3(0) -y = -15
0 -y = -15
-y = -15
y=15

Answer 10

the y-intercept is 15. Put it in y=mx+b form and you will see this.
