Answer:
Step-by-step explanation:
The slope form of an equation of a line:
<em>m</em><em> - slope</em>
<em>b</em><em> - y-intercept</em>
We only need two points to draw a line.
Convert to the slope-intercept form.
<em>add y to both sides</em>
<em>subtract 4 from both sides</em>
Choice two values of x, put to the equation y = 2x - 4:
for x = 0
for x = 2
<em>add y to both sides</em>
<em>add 2 to both sides</em>
y = 2x + 2
for x = 0
for x = 2
<, > - dotted line
≤, ≥ - solid line
<, ≤ - we shade the region below the line
>, ≥ - we shade the region above the line
dotted line passes through (0, -4) and (2, 0), we shade the region below the line
dotted line passes through (0, 2) and (2, 6), we shade the region above the line
