# What is the equation of the line described below written in slope-intercept form? the line passing through point (2, 4), parallel to the line whose equation is y = x

The slope of $y=x$ is 1, so the slope of the other line is also 1. We have $y=x+b$ To find $b$, we plug in $(2, 4)$: $4=2+b$ $\rightarrow b=2$ So the equation is $y=x+2$
