Answer:
compare the distance between the lines at one point to the distance between the lines at another point
Step-by-step explanation:
You can construct perpendiculars at different points and compare the distance between the lines at those perpendiculars. The distance between parallel lines is the same everywhere.
Answer:
3x4=12 is 300x400=1200 but it is not multiplied by 100
Step-by-step explanation:

Step-by-step explanation:
Let's first get the slope of the curve.
[ slope is the derivative of the equation ]

introduce dy/dx :

make dy/dx the subject:

At point (-1, 2):

but a tangent has the same slope as the curve:

m is the slope
c is the y-intercept
At (-1, 2):

equation:
