What is an equation of a line that passes through points (-5,1) and (5,3)​

  y = 1/5x +2

Step-by-step explanation:

The 2-point form of the equation for a line can be a good place to start.

  y = (y2 -y1)/(x2 -x1)(x -x1) +y1

  y = (3 -1)/(5 -(-5))(x -(-5)) +1 . . . . fill in values

  y = 2/10(x +5) +1 . . . . . . . . simplify a bit

  y = 1/5x + 2

i can't read the graph

step-by-step explanation:

there is only one way to arrange all the eight relative to each other because they are not distinct. we have

now there are nine places to place an (and not more than one in one place).   because we have four symbols, we need to choose four of these nine places to insert an . order does not matter because the are not distinct.

thus there are 1 · c(9,4) ways, or, if we calculate it,

thus there are 126 ways to form such "words."
