Question

Write the equation of the line represented by the following table.

Answer 1

take two points \((x_0,y_0),(x_1,y_1)\) and get the slope \(m=\frac{y_1-y_0}{x_1-x_0}\) and tell me what you get.

Answer 2

i got 100

Answer 3

ok that is the slope. now we need the point \((0,b)\)

what is \(b\)?

Answer 4

do you mean 400 because it is the one in the graph?

Answer 5

yeah

Answer 6

so the equation is \(y=mx+b\) and you know what m, and b are

Answer 7

so it is the slope and the y-intercept?

Answer 8

is it y=100x+400

Answer 9

yes

Answer 10

thanks theres a medal :D

Answer 11

hehe no prob.

easy peasy, just find slope and intercept then use "slope intercept" form
