Answer:
Y=mx+b Is a linear equasion because if you plot the x and y on a graph it always shows a straight line.
Step-by-step explanation:
For example, y=7x+9,
When x is 1 y is 16, and
when x is 2 y is 23.
When you put those two points on a graph and connect the dots with a ruler, you get a straight line, and you will automatically find that when x is 3 y is 30.

Answer:
<h3>Attachment</h3>
Step-by-step explanation:
Convert to the slope-intercept form (<em>y = mx + b</em>):
<em>divide both sides by 2</em>

We choose any three x values and calculate the y value:
for x = -1

for x = 1

for x = -3

Mark the points on the coordinate plane and draw a line through the given points.
This is Transitive Property.
Blame me if you get it wrong :\
