$y = 0.3 x + 25$

Short Answer

The required graph of line is:

Step by step solution

Step 1. Given information.

The equation $y = 0.3 x + 25$ .

Step 2. Find slope and y-intercept.

Compare the given equation $y = 0.3 x + 25$ with slope-intercept form $y = m x + b$ .

$m = 0.3; b = 25$

So, slope is $0.3$ and y-intercept is 25.

Step 3. Graph the line using y-intercept and slope.

Plot the y-intercept $(0, 25)$ and for second point, use the slope which is given as $0.3 = \frac{3}{10}$ that is;

$r i s e = 3, r u n = 10$

So, plot the second point at $(10, 28)$ .

Then, graph the line joining these two points:
