How do you graph y= 3x-2

Step-by-step explanation:

start at -2 on the y axis and go up 1 to the right 3 and so on

Plug in x values into the equation. Start by making a table with x on one side and y on the other. Then, plug in an x value into the equation. We'll start by plugging in 0. This would give us y=3(0)-2, which simplifies to y=-2. Now we know that when x=0, y=-2, so write these two values in your table. Next, we can do this with more points. Let's plug in 1 for x. This gives us y=3(1)-2, which simplifies to y=1 when x=1. Again, we'll write this in our table. After we have a few pairs of x and y values, then we'll draw these points on the graph.

Step-by-step explanation:

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
