CPM Homework Help : MC2 Problem 6-114

On graph paper, graph the rule $y = 4x-6$ . Determine the value of y when $x = \frac { 1 } { 2 }$ .

Step 1:

Make a table of $x$ -values and their corresponding $y$ -values.
(To find the $y$ -coordinate of an $x$ -value, substitute the $x$ -value
into the expression and solve.)

Step 2:

Plot these points onto your graph.(For this sample graph, we will only
plot $3$ points.)

Step 3:

Draw a straight line that intersects all the points
plotted with arrows at the end to show that the
rule continues.
NEXT: Estimate the $y$ -value when the graph intersects $x = 0.5$ .
