Does this graph represent a function? Why or why not?

Mathematics
1 answer:
vlabodo [156]4 years ago

Answer:

A

Step-by-step explanation:

In order for a graph to be a function, it has to only cross the vertical (up and down) lines that it covers once. Since this is an angle, it crosses all the lines in two different places, and isn't a function.

Why do you think y= ax+b is called a linear equation <br> Please help
Shalnov [3]

Answer:

Y=mx+b Is a linear equasion because if you plot the x and y on a graph it always shows a straight line.

Step-by-step explanation:

For example, y=7x+9,

When x is 1 y is 16, and

when x is 2 y is 23.

When you put those two points on a graph and connect the dots with a ruler, you get a straight line, and you will automatically find that when x is 3 y is 30.

lions [1.4K]

Answer:

60

Step-by-step explanation:

Since the hypotenuse of a right triangle is the longest side, 17 is the longest. So 8 and 15 are the legs. Since the area of a triangle is 1/2bh, then the area of the Stainglass is 1/2*8*15. So the area of the piece is 60.
