Y=mx+b is The equation of any straight line, called a linear equation, can be written as: y = mx + b, where m is the slope of the line and b is the y-intercept. The y-intercept of this line is the value of y at the point where the line crosses the y axis.

y = mx + b is what's called the slope formula.

It's used for when you want to know what the formula for a line is.

y is just the y value.

Sometimes, a question will ask for you to find a line with some slope and going through some point. In this case, you would replace y with the y value of that point.

However, when you're finished with your equation, y should always be a variable.

m is the slope.

To find the slope, you have to use the point-slope formula. When given two points, you put them into this equation: \frac{y_2-y_1}{x_2-x_1}

When you're finished with your equation, m should be a number.

x is just the x value.

Sometimes, a question will ask for you to find a line with some slope and going through some point. In this case, you would replace x with the x value of that point.

However, when you're finished with your equation, x should always be a variable.

b is the y-intercept, or when x = 0.

This is usually what you'll need to find in y = mx + b. What will likely happen is you'll given everything but b. All you need to do then is plug in the values you're given into this equation.

When you're finished with your equation, b should be a number.

If you have any questions, let me know! I'm happy to edit my response with more information if need be.

How to find only f on a graph that defines a function
puteri [66]

Answer:

Read Below

Step-by-step explanation:

we can represent a function using a graph. Graphs display many input-output pairs in a small space. The visual information they provide often makes relationships easier to understand. We typically construct graphs with the input values along the horizontal axis and the output values along the vertical axis.

The vertical line test can be used to determine whether a graph represents a function. A vertical line includes all points with a particular

x

value. The

y

value of a point where a vertical line intersects a graph represents an output for that input

x

value. If we can draw any vertical line that intersects a graph more than once, then the graph does not define a function because that

x

value has more than one output. A function has only one output value for each input value.

In triangle MNP, m = 5 cm, n = 4 cm, and p = 8 cm. Which formula can you use to find P?
charle [14.2K]
Answer:
8² = 4² + 5² - 2(4)(5) cos(P)
which is the third option

Explanation:
The general rule of cosine is:
a² = b² + c² - 2bc*cos(A)

In our triangle:
a is substituted by p = 8 cm
b is substituted by n = 4 cm
c is substituted by m = 5 cm
A is substituted by P which we want to find

Replace the variables in the general equation with the givens as follows:
p² = n² + m² - 2mn*cos(P)
8² = 4² + 5² - 2(4)(5) cos(P)

Hope this helps :)
