Is this a function or not​

Mathematics
1 answer:
Marta_Voda [28]3 years ago
3 0

Answer:

No, I don't think so.

Step-by-step explanation:

I don't think this is a function because the triangle is made of multiple points. Some of these points share the same <em>x</em> point, so this concludes that a triangle on a graph is not a function.

Hope it helps!

Write the equation of the line that passes through the points (2, 1) and (5, -8)
My name is Ann [436]

Answer:

The answer is y = -3x + 7.

Step-by-step explanation:

❃Incase you forgot what the linear equation formula is ☟

y = mx + b

❃Incase you also forgot, what the slope formula is ☟

m =  \frac{y_2 - y_1}{x_2 - x_1}

➊ First: We are going to be solving for the slope.

m =  \frac{ - 8 - 1}{5 - 2}  =  \frac{ - 9}{ \:  \:  \: 3}  =  - 3

➋Second: We find the y-intercept.

y = mx + b \\ 1 = - 3(2) + b \\ 1 = - 6 + b \\ \frac{ + 6 = + 6 \: \: \: \: \:  \:  \:  \:  \: }{7 = b}

➌Third: Plug in.

y =  - 3x + 7

Write an inequality to represent the graph below.
Yanka [14]

Answer:

The answer to your question is letter C

Step-by-step explanation:

Process

1.- Find two points of the line

A ( 0, -3)   B ( 2, 2)

2.- Find the slope of the line

    m = \frac{y2 - y1}{x2 - x1} = \frac{2 + 3}{2 - 0}

    m = \frac{5}{2}

3.- Find the equation of the line

    y - y1 = m(x - x1)

    y + 3 = 5/2(x - 0)

    y + 3 = 5/2 x

    y = 5/2 x - 3

4.- Convert the line to an inequality, we want the upper area so use ">"

    y > 5/2 x - 3
