It’s going to be (1/8)x or x/8...

$\bf \stackrel{\textit{perpendicular lines have \underline{negative reciprocal} slopes}} {\stackrel{slope}{-8\implies \cfrac{-8}{1}}\qquad \qquad \qquad \stackrel{reciprocal}{\cfrac{1}{-8}}\qquad \stackrel{negative~reciprocal}{\cfrac{1}{8}}}$

What is the slope intercept of a line perpendicular to the line y=2x+3 with the point (-2,-4)

olchik [2.2K]

Answer:

y = - $\frac{1}{2}$ x - 5

Step-by-step explanation:

the equation of a line in slope-intercept form is

y = mx + c ( m is the slope and c the y-intercept )

y = 2x + 3 is in this form with slope m = 2

given a line with slope m then the slope of a line perpendicular to it is

$m_{perpendicular}$ = - $\frac{1}{m}$ = - $\frac{1}{2}$

y = - $\frac{1}{2}$ x + c ← is the partial equation

To find c substitute (- 2, - 4) into the partial equation

- 4 = 1 + c ⇒ c = - 4 - 1 = - 5

y = - $\frac{1}{2}$ x - 5 ← equation of perpendicular line

Franklin the fly starts at the point $(0,0)$ in the coordinate plane. At each point, Franklin takes a step to the right, left, u

Anastaziya [24]

Answer:

80 different points.

Step-by-step explanation:

right, left, up, or down = 4 possibilities x 2 since there is a coordinate with 2 numbers so,

8 possibilities.

8 x 10 = 80 possibilities.
