Question

Find the equation of the line use exact numbers
Y=_x+_

Answer 1

Y = 2x + 4

Explanation:

y= mx +b

First, find m (aka the slope)

`(rise)/(run)` =
`(2)/(1)` = 2

m = 2

Find b (aka the y-intercept)

The line touches the y-axis at (0,4). Therefore b = 4

Plug m and b into the slope-intercept equation

y = mx +b

y = 2x + 4
