Question

IMPORTANT - ALGEBRA I PLEASE HELP

A line passes through the origin and the point (4,8). Show how you can use this information, an arbitrary point (x,y) other than the origin,and the slope formula to find an equation of the line. Then rewrite the equation in the form of y=mx + b

Answer 1

Welcome to Openstudy!!!

Answer 2

not really new, just had to make a new account because i have't used this site in almost 2 years, but thanks!

Answer 3

what are the coordinates for the origin?
how do you find the slope of a line?

Answer 4

origin: 0,0
To find the slope, you will need two points from the line. Pick two x's and solve for each corresponding y

Answer 5

what do you know about the points on a line in relation to the slope?

Answer 6

what do you mean by that?

Answer 7

use the proper notation please

Answer 8

how do you write the coordinates of a point?

Answer 9

(0,0) why is that relevant?

Answer 10

great practice to do it correctly

Answer 11

what are your points?
what is the equation for the slope?

Answer 12

you do not solve for y after you pick your x's
coordinates are (x,y)

Answer 13

you cannot solve unless you already have the equation of the line?

Answer 14

making more sense now?

Answer 15

you did not answer how do you find the slope of a line? what do you know about points on the line in relation to the slope?
