Find an equation for a line perpendicular to y= 3x – 5 , with a y- intercept of -2

Mathematics

Answer:

Since the lines are Perpendicular..

The Product of their Gradients = -1

m'm"=-1

m' from y=3x - 5 is 3

3.m" = -1

m" = -1/3.

Since Intercept on y axis = -2...

That of x at that point is =0

y-y' = m"(x-x")

y-(-2) = -1/3( x - 0)

y+2 = -1/3(x)

Multiplying through by 3

3y + 6 = -x

3y + x = -6. This is your Equation

To verify this.

Let's turn it into the Intercept form which is

x/a + y/b = 1

To get 1 at the right hand side... Divide through by -6

3y/-6 + x/-6 = 1

y/-2 - x/6 = 1

You could see directly below y is its intercept and thats -2

-8w-7+2w=23 what does that equal
olya-2409 [2.1K]
W=-5 because you distribute at the beginning with the 2 variables and you solve that's equation and you will end up with 6w divided by 30 and that's will give u W=-5

    ¹/₅                                        20%                                           0.2

    ¹/₄                                        25%                                         0.25

    ¹/₂                                        50%                                           0.5

    ²/₃                                      66.6%                                        0.6

Fraction;

25/100 = 1/4

66.6/100 = 2/3

Percentage

1/5 * 100 = 20%

1/2 * 100 = 50%

Decimal

1/5 = 0.2

25/100 = 0.25

1/2 = 0.5
