Chapter 4: Q. 4.80 (page 499)

Use the graph to find the slope and y-intercept of the line $y = \frac{1}{2} x + 3$ . Compare these values to the equation $y = m x + b$ .

Short Answer

Expert verified

The solution is slope $= \frac{1}{2}$ and y-interceptrole="math" localid="1651561026257" $= (0, 3)$ .

Step by step solution

Step 1. Given information

Line: $y = \frac{1}{2} x + 3$

Step 2. Calculation

Use the points $(0, 3)$ and $(2, 4)$ on the line.

Here, $m = \frac{r i s e}{r u n}$

$m = \frac{1}{2}$

The y-intercept is the point $(0, 3)$ .

Now compare, $y = \frac{1}{2} x + 3$

$y = m x + b$

The slope is the same as the coefficient of x and the y-coordinate of the y-intercept is the same as the constant term.
