1 answer:
Mekhanik [1.2K]2 years ago
4 0

Answer:

Step-by-step explanation:

Perpendicular lines are lines whose slopes are negative reciprocals of each other

To find the slope of the line we are given, we can rearrange the equation

4x - 5y = 4\\4x - 4 = 5y\\y = \frac{4}{5}(x) - \frac{4}{5}

The slope of this line is \frac{4}{5}, so the slope of the other line is \frac{-5}{4}

next, we can use the given point to find the equation y = mx +b

we know m, we can solve for b

y = \frac{-5}{4}(x) + b\\-3 = \frac{-5}{4}(-2) + b\\-3 = \frac{5}{2} + b\\\frac{-6}{2} = \frac{5}{2} + b\\

b = \frac{-11}{2}

so,\\y = \frac{-5}{4}(x) - \frac{11}{2}

Graph the equation using the slope and the y intercept 2x-3y=8
sammy [17]

Step-by-step explanation:

<h2>Find slope-intercept structure </h2>
  • y=
  • \frac{2}{3} x -  \frac{8}{3}
  • m=2/3, b=-8/3
  • therefore the slope will be 2/3

To find y-intercept

  • let x=0
  • 2(0)-3y=8
  • -3y=8
  • y=-3/8

To find x-intercept

  • let y=0
  • 2x-3(0)=8
  • 2x=8
  • x=4

-5/4-(-1/6) help please
tiny-mole [99]
A way to add fractions that always works is to multiply each numerator by the denominator of the other, then express the sum of products over the product of the denominators.
\dfrac{a}{b}+\dfrac{c}{d}=\dfrac{a}{b}\cdot\dfrac{d}{d}+\dfrac{c}{d}\cdot\dfrac{b}{b}\\\\=\dfrac{ad+bc}{bd}

Here, you have
\dfrac{-5}{4}-\dfrac{-1}{6}=\dfrac{-5\cdot6-(-1)\cdot4}{4\cdot6}=\dfrac{-26}{24}\\\\=\dfrac{-13}{12}=-1\frac{1}{12}

The sum is -1 1/12

Use the table below to determine whether f(x) could represent a linear function If it could write f(x) in the form f(x)=mx+b
Elodia [21]

Answer:

  • f(x) = 6x - 5

Step-by-step explanation:

We see f(x) increase is linear and is 6 at each step, so m = 6 and y-intercept is b = -5, from point (0, -5)

<u>So the function is:</u>

  • f(x) = 6x - 5
