Answer:
I believe the answer is B or C, but i pretty sure it is B.
Answer:
y = -2x - 3
Step-by-step explanation:
-solve for y: y = 1/2x + 2
-perpendicular equals opposite slope: -2
-plug in the point: (1) = -2(-2) + b
1 = 4 + b
b = -3
put it all together: y = -2x - 3
Hi there! The answer is y = -3x - 21
Let's set up the equation of the line step by step! First we need to know that we need to set up an equation in slope-intercept form. We get the following:
y = ax + b.
a represents the slope of the line.
b represents the intercept with the y-axis.
Since our new line is parallel to y = -3x + 1, both lines have the same slope. Therefore the slope of our line, which is represented by a, is -3.
y = -3x + b.
We also know that this line goes through the point (-5, -6) and therefore we can plug in these coordinates into our formula.
-6 = -3 × -5 + b
Simplify
-6 = 15 + b
Subtract 15
-21 = b
Switch sides
b = -21
Hence, y = -3x - 21

Alright lets break it down:
Carol = 60 inches tall
Mindy = ??
Lets turn words into numbers:
60 inches is 20 inches less than (2x) Mindy's height
60 inches + 20 inches = 80 inches
This helps us visualize it better, if 60 is 20 inches less than two times Mindy's height, then that means 80 is two times Mindy's height, right?
80 ÷ 2 = 40 inches
Mindy's height is 40 inches
If this is still unclear, comment back.
Hope I was of use, best of luck.
