Tell whether the lines are parallel, perpendicular, or neither.
the line through (-3, 2) and (4, 6) and the line through (-5, 7) and (-9, 14)

perpendicular

Step-by-step explanation:

We only need the slope for this question. When we write in point-slope form, we can get the slope easily.

2-6 / -3-4 = -4 / -7 = 4/7 #The 1st line of slope

7-14 / -5-(-9) = -7 / 4 = -7/4 # The 2nd line of slope

So we can notice that the 1st slope is "upside down" and positive turns negative. So these lines are perpendicular.

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
