No.147 Drawing Graphs of Linear Functions
POINT
In \(y=ax+b\), \(a\) is the slope and \(b\) is the y-intercept. Plot the y-intercept first, then use the slope to locate another point.
Example
Draw the graph of each linear function.
① \(y=2x-3\)
② \(y=-3x+2\)
③ \(y=\frac23x+1\)
④ \(y=-\frac12x-2\)
TRY
TRY 1
Draw \(y=3x+1\).
TRY 2
Draw \(y=-\frac23x+2\).
