2.4 quick Graphs of linear<br />
Equations<br />
Goal p Use slope-intercept form and standard form to<br />
graph equations.<br />
Vocabulary<br />
y-intercept The y-coordinate of a point where a<br />
graph intersects the y-axis<br />
Slope-intercept form A linear equation written in the<br />
form y 5 mx 1 b where m is the slope and b is the<br />
y-intercept of the equation’s graph<br />
x-intercept The x-coordinate of a point where a<br />
graph intersects the x-axis<br />
Standard form of a linear equation A linear equation<br />
written in the form Ax 1 By 5 C where A and B are<br />
not both zero<br />
GraphinG EquaTionS in SlopE-inTErcEpT Form<br />
Step 1 Write the equation in slope-intercept form by<br />
solving for y .<br />
Step 2 Find the y-intercept and plot the<br />
corresponding point.<br />
Step 3 Find the slope and use it to plot a second<br />
point on the line.<br />
Step 4 Draw a line through the two points .<br />
