Answer:
the bottom left one (the graph that looks like a circle) is not a function, but the other ones are.
Step-by-step explanation:
A function is defined so that for every x value within a function has a y value. This means that an x value CANNOT have more than one y value. The bottom right one has two y values for almost every x value within the domain. The top ones are functions, because all x values have only 1 y value (a discontinuous function is still a function!) And the bottom right is too.
You can solve an easy equation in your head by using the multiplication table.
Answer:
The equation of the line would be y = -2x + 3
Step-by-step explanation:
In order to find the equation of the line, start by using point-slope form with the known information.
y - y1 = m(x -x1)
y - 1 = -2(x - 1)
Now that we have this, solve for y.
y - 1 = -2x + 2
y = -2x + 3
I’d like to answer the but What angle ??
