The graph of a linear function has a slope of 1/4 and passes through the point (1,3). What is the y-intercept of the function?

Vikki [24]

Answer:

Step-by-step explanation:

In slope intercept form, y = mx + b, the m is the slope, the b is the y intercept, and x and y can be subbed in from the point you are given of (1, 3). We are told the slope, so everything we have fills in like this:

$3=\frac{1}{4}(1)+b$

Now we just need to solve for b:

$3-\frac{1}{4}=b$ and

$\frac{12}{4}-\frac{1}{4}=b$ so

$b=\frac{11}{4}$

If axb=0, then a=0 or b=0 3x=0

stepladder [879]

Answer:

The given equation is

ax b= 0,

As we see that, it is a linear equation in one variable containing two constant.

So , a≠ 0 [then equation has no meaning.If a=0 , then $0 \times x=0$ , which is meaningless]. ∴ a=0 is incorrect.

Similarly , b≠ 0 [ Reason same as above]. ∴b=0 is incorrect.

⇒3 x=0

⇒x=0 is the correct response.

Let me explain by this giving an example

⇒5 x=0

⇒ x=0 but 5≠0

So, x=0 or 3 x=0 is correct response.

Which function has an inverse that is also a function? {(–4, 3), (–2, 7), (–1, 0), (4, –3), (11, –7)} {(–4, 6), (–2, 2), (–1, 6)

9966 [12]

Answer:

1. {(–4, 3), (–2, 7), (–1, 0), (4, –3), (11, –7)}

Step-by-step explanation:

Info to consider:
Inverse of a function: (x, y) → (y, x)
Definition of a function: Every input will have exactly one output.

Let's analyze the functions:

1. {(–4, 3), (–2, 7), (–1, 0), (4, –3), (11, –7)}

It has unique y- values, its inverse won't have repeat x-values, so the inverse is also a function

2. {(–4, 6), (–2, 2), (–1, 6), (4, 2), (11, 2)}

It has repeat y values of 6 and 2. Its inverse it is going to cause repeat input numbers with different output. This won't be a function

3. {(–4, 5), (–2, 9), (–1, 8), (4, 8), (11, 4)}

It has repeat y values of 8. Its inverse it is going to cause repeat input numbers with different output. This won't be a function

4. {(–4, 4), (–2, –1), (–1, 0), (4, 1), (11, 1)}

It has repeat y values of 1. Its inverse it is going to cause repeat input numbers with different output. This won't be a function

So the first set of data is the only correct one
