Problem
Find the slope and $y$-intercept of the line whose equation is $y=4 x+5$. What is the slope? Select the correct choice below and, if necessary, fill in the answer box to complete your cho A. The slope is 4 . (Type an integer or a fraction.) B. The slope is undefined. What is the $y$-intercept? Select the correct choice below and, if necessary, fill in the answer box to complete yo A. The $y$-intercept is $\square$. (Type an ordered pair.) B. There is no $y$-intercept.
Solution
Step 1 ：Compare the given equation y = 4x + 5 to the standard form y = mx + b
Step 2 ：Identify the slope as 4
Step 3 ：Identify the y-intercept as (0, 5)
