Using slopes and intercepts
100
Tell if it's linear y=x+1
linear

What is slope?
The slope of a line is the ratio of rise to run for any two points on the line
200
Tell if its linear y=x^3
Not linear
200
What is rise?
The rise is the difference of the y-values of two points on a line
200

the x-intercept with a line passing through the point (7,0)

what is 7

300
Tell if it's linear y=1/4x-1
linear
300
What is run?
The run is the deference in the x-values of two points on a line.
300
find the x-intercept(Y=0) 3x+4y=12
the x-intercept is 4
400
Tell if it's linear y=x^2-12
Not linear
400
find the slope (2,5) and (3,6)
The slope is 1
400
find the y-intercept(x=0) 3x+4y=12
The y-intercept is 3
500
Tell of its linear y=1/3x^2
Not linear
500
Fine the slope (-2,-2) and (-4,1)
the slope is -3/2
