Question

PLEASE HELP ME FAST!!! ( It's about finding linear equations on a graph)

Answer 1

y = 7x

Explanation:

The equation of a line passing through the origin is

y = mx ( m is the slope )

Calculate m using the slope formula

m =
`(y_(2)-y_(1) )/(x_(2)-x_(1) )`

with (x₁, y₁ ) = (0, 0 ) and (x₂, y₂ ) = (100, 700 ) ← 2 points on the line

m =
`(700-0)/(100-0)` =
`(700)/(100)` = 7

y = 7 x ← equation of line
