So your goal is to make (x-4) equal 0. Just this of the number that cancels -4 out so you’ll be left with a zero in the parentheses: (4-4)(4-4)=0. So you’ll have (0)(0)=(0). We know that 0 times 0 is zero, so you’ll end up with 0=0 and since that is a true statement, x=4.

Answer:

x = 4

Step-by-step explanation:

<u>Step 1: Set both parts equal to 0</u>

x - 4 = 0 and x - 4 = 0

<u>Step 2: Solve for x by adding 4 to both sides</u>

x - 4 + 4 = 0 + 4 and x - 4 + 4 = 0 + 4

x = 4 and x = 4

Answer: x = 4

We are given with the coordinates of one of the points of a line which is
(1,2)
In order to generate an equation of a line, we need at least one other point or the slope of the line. If we are given with the slope of line, we can use the point slope form which is
y - y1 = m (x - x1)
substituting
y - 2 = m(x - 1)
