Lines are described by equations of the form y = mx + b
The fast way of finding 'b' is to look for a place where x = 0 and plug in the x and y values into this equation. In the case of this line, when x = 0, y = 5:

5 = m(0) + b
5 = 0 + b
5 = b

To get the slope, 'm', we need to pick two points and divide the difference of their y values by the difference of their x values. Pick points where the line falls on the grid. The one we just used, (0,5), works well. So does (2,1).

Plug into the equation m = (y2-y1)/(x2-x1) to get m = (1-5)/(2-0) = -4/2 = -2

Our equation is y = -2x + 5

Right triangle ABC has a right angle at ∠B and the following measures: AB=37, m∠C=65°, and m∠A=25°.
julia-pushkina [17]

Answer: option B is the correct answer.

Step-by-step explanation:

Triangle ABC is a right angle triangle.

From the given right angle triangle,

AC represents the hypotenuse of the right angle triangle.

With m∠C as the reference angle,

BC represents the adjacent side of the right angle triangle.

AB represents the opposite side of the right angle triangle.

To determine m, we would apply

the Tangent trigonometric ratio.

Tan θ, = opposite side/adjacent side. Therefore,

Tan 65 = 37/m

m = 37/Tan65

m = 37/2.1445

m = 17.25

Graph the relation. Is the relation a function? Why or why not? {(0, 1), (3, 5), (2, 2), (–1, 4)}
vagabundo [1.1K]

Answer:

It is a function.

Step-by-step explanation:

This relation <u>is</u> a function because it does not repeat any x values in the set of data points.

A function is a set of points where the input values, or x values, do not repeat themselves.

Hope this helps!
