Pls help I dont get it​

Answer 1

y=4x

Explanation:

The equation of a line is y=mx+b, where m is the slope and b is the y intercept.

The slope formula is Δy/Δx, so using the coordinates (1, 4) and (2, 8), the slope is
`(8-4)/(2-1)` which equals 4.

The y intercept is 0.

Therefore, the equation is y=4x.
