True or false? top or bottom.
1)a straight line on a coordinate plane always represents a function.
or
2)the equation y=2x+1

1) is not true. straight lines are not always functions, because for a line to be a function, it must pass the "vertical line" test. x = 1, for example, is a vertical line, and it does NOT pass the vertical line test, but it IS a straight line. this example shows that the first is false.

2) doesn't look like the complete choice, but if it's asking whether or not y = 2x + 1 is a function, the answer is yes. you can know this by plugging it into a grapher and seeing that it's a line that passes the vertical line test (aka, making it a function).

Well what if i told you it wouldn’t matter, because in the future the pony dies, depending on what choice you make
