Question

if the slope of a line is 2 and its y-intercept is 5, what is the equation of the line?

Answer 1

$The\ slope-intercept\ form:y=mx+b\\\\m=2;\ b=5\\\\\boxed{y=2x+5}$

Answer 2

Answer:

y=2x+5

Step-by-step explanation:

A straight line can be defined as:

$y=m*x+c$

Where m is the slope of the line and c the y-intercept when x=0. Therefore:

$y=2*x+5$

We can prove the y-intercept by making x=0:

$y=2*0+5=5$
