Solution:
Any line of the form is a straight line and has a slope m , where b is the y- intercept.
To find out the y-intercept of the equation .
On comparison above equation with , we have b=4.
Therefore, we have the y-intercept of the given function is 4.
Step-by-step explanation:
For this case we have to;
We have that an equation in slope-intercept form is given by:

Where:
m is the slope
b is the cut point with the y axis
Also, by definition, two lines are perpendicular when the product of their slopes is -1. That is:
We have the line as data: 
Then 
We found
:





Thus, 
We must find
:
We know that
passes through the point
We substitute the point in the equation of
:

Thus, 
Then the equation in slope-intercept for the line that passes through (5,0) and is perpendicular to the line described by
is:

Step-by-step explanation:
Answer:
- x = 0 or 1
- x = ±i/4
- x = -5 (twice)
Step-by-step explanation:
Factoring is aided by having the equations in standard form. The first step in each case is to put the equations in that form. The zero product property tells you that a product is zero when a factor is zero. The solutions are the values of x that make the factors zero.
1. x^2 -x = 0
x(x -1) = 0 . . . . . x = 0 or 1
__
2. 16x^2 +1 = 0
This is the "difference of squares" ...
(4x)^2 - (i)^2 = 0
(4x -i)(4x +i) = 0 . . . . . x = -i/4 or i/4 (zeros are complex)
__
3. x^2 +10x +25 = 0
(x +5)(x +5) = 0 . . . . . x = -5 with multiplicity 2

Write in expanded form
First, we need the place value of each digit:

Next, we multiply each digit by its place value, to give the expanded form;
