A ladybug and ant move at constant speeds. The diagrams with tick marks show their positions at different times. Each tick mark
represents 1 centimeter.
In your textbook pg. 111, scale the vertical and horizontal axes by labeling each grid line with a number. You will need to use the time and distance information in the tick-mark diagrams.
Which line shows the ladybugs movement? The ant?
Unit rate for the Ladybug? The ant?
How long does it take for the ladybug to travel 12 cm? The ant?

The point-slope form of the equation of a line is
where
is a point on the line, and
is the slope of the line.
We can use either one of the two given points as the point on the line.
We also need to find the slope. We can use the coordinates of the two given points to find the slope of the line.
The slope of the line that passes through points
and 
is
Let's find the slope using (-3, 5) as point 1 and (-1, 4) as point 2.
Now we use the point-slope formula with point 1 and the slope we found just above.
