how do you find the slope of a line, I know you have to use y=mx + b but where do you get the numbers and stuff, like how do you plug it in.

when you have a point, it is a coordinate pair. in other words, it represents an x coordinate and a y coordinate that go together. it says, for (x,y), when you put x into your equation, the result will be y. thus, you can just put your point for the x and y values in the equation.

ex. (1,6)

when x = 1, y = 6

6 = m(1) + b

hope this helps <3

it is probably the graph on the bottom right.
