18) Write an equation of the line that is perpendicular to the line y = 4x - 10 that passes through the point (-16, 2). A) y = - 1 4 x - 2 B) y = -4x + 6 C) y = - 1 4 x + 2 D) y = 4x + 2

Slope-intercept form:  y = mx + b

(m is the slope, b is the y-intercept or the y value when x = 0 --> (0, y) or the point where the line crosses through the y-axis)

For lines to be perpendicular, their slopes have to be negative reciprocals of each other. (flip the sign +/- and the fraction(switch the numerator and the denominator))

For example:

Slope = 2 or  

Perpendicular line's slope =  (flip the sign from + to - , and flip the fraction)

Slope =

Perpendicular line's slope =  or  3  (flip the sign from - to +, and flip fraction)

y = 4x - 10     The slope is 4, so the perpendicular line's slope is .

Now that you know the slope, substitute/plug it into the equation.

y = mx + b

  To find b, plug in the point (-16, 2) into the equation, then isolate/get the variable "b" by itself

 (two negative signs cancel each other out and become positive)

2 = 4 + b      Subtract 4 on both sides to get "b" by itself

2 - 4 = 4 - 4 + b

-2 = b

    Your answer is A

1/8 3/16 3/4

step-by-step explanation:

you put them as all the same denominator and multiply

ratio is 2 : 9

the answer is three

13.5 : 3
