Question

Slope of a line is $3$ and y intercept is $-4$. Write the equation of a line.

Answer 1

We know that the linear equation of a line is: $y=mx+c$, where $m$ is the slope and $c$ is your y-intercept

So, we just plug the numbers into the equation, $m=3,c=-4$, we get $y=3x-4$

Hence the equation of the line is $y=3x-4$
