Answer:

Never

Step-by-step explanation:

If the slope is the same and the y-intercept is the same

They are the same line

2x + 5 = y is the same as 2x +5 = y

A factory makes 640brushes in 4 hours.Does the equation y=150x model the number of brushes made each hour?

adelina 88 [10]

Answer:

No it doesn't

Step-by-step explanation:

The equation we have is

Y = 150x

We have x = 4 hours

This is a simple question. We have to plug in the x = 4 in the equation to find out if we would have 640 brushes. If y = 640, then it models it. But if y is not equal to 640, it doesn't.

So let's solve this to see for ourselves.

Y = 150(x)

We put the value of x

Y = 150(4)

Y = 600

So we can see that the equation does not model the number of brushes made each hour. This equation models 600 brushes and not 640.

The<br> What is the slope of the line?

Shtirlitz [24]

Answer:

-1

Step-by-step explanation:

Slope is calculated with the general equation $\frac{x_{2}-x_{1} }{y_{2}-y_{1}}$ where you compare the difference between two sets of data points on the slope.
