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 the negative reciprocal of each other. (Basically flip the sign +/- and the fraction[switch the numerator and the denominator])

For example:

Slope = \frac{1}{3}

Perpendicular line's slope = -\frac{3}{1}  or  -3

Slope = -2 or -\frac{2}{1}

Perpendicular line's slope = \frac{1}{2}

y=\frac{1}{3} x+5    The given line's slope is \frac{1}{3}, so the perpendicular line's slope is -3. Now that you know the slope, substitute/plug it into the equation:

y = mx + b

y = -3x + b    To find b, plug in the point (1, 9) and isolate/get the variable "b" by itself in the equation

9 = -3(1) + b      Add 3 on both sides to get "b" by itself

9 + 3 = -3 + 3 + b

12 = b

y = -3x + 12

Bailey has a video streaming service with a flat monthly fee of $18.00 plus an additional cost of $3.50 for each premium movie r
brilliants [131]

Answer:

3.50 x+18.00 ≤ 40.00

Step-by-step explanation:

She pays 18 dollars each moth, therefore that quantity won't change, so you will have to add. Each movie that she watches is an additional 3.50, then we have 3.50 x, x being the quantity of movies that she watches. She can only afford up to 40 dollars, then everything that she spends has to be less or equal to 40.
