What is the equation of the line with the same slope as the equation x-4y=3 and the y-intercept(0,-8)?
katen-ka-za [31]

Answer:

y = 1/4x -8

Step-by-step explanation:

First find the slope of the line

x-4y =3

Subtract x from each side

x-4y -x = -x+3

-4y = -x+3

Divide each side by -4

-4y/-4 = -x/-4 +3/-4

y = 1/4 x -3/4

This is in the form y= mx+b where the slope is m and the y intercept is b

The slope is 1/4

We want the same slope

y = 1/4x +b

we know the y intercept is -8

y = 1/4x -8

The equation y=2(x-1)^2-5y=2(x−1)
marin [14]

Answer:

(b) It is symmetrical about x = 1

Step-by-step explanation:

Given

y = 2(x - 1)^2 - 5

See attachment for options

Required

True statement about the graph

First, we check the line of symmetric

y = 2(x - 1)^2 - 5

Expand

y = 2(x^2 - 2x + 1) - 5

Open bracket

y = 2x^2 - 4x + 2 - 5

y = 2x^2 - 4x -3

A quadratic equation y = ax^2 + bx + c has the following line of symmetry

x = -\frac{b}{2a}

By comparison, the equation becomes:

x = -\frac{-4}{2*2}

x = \frac{4}{4}

x = 1

Hence, the line of symmetry is at: x = 1

(b) is true.
