point slope form formula { (y-y1) = m (x-x1) }
so 1. (y-3) = 1/8 (x-3)
2. ( y- 30 ) = -4 (x-6)
3. ( y -7) = 0.25 (x +8)
4 . ( y -2 ) = 1 ( x-0)
Slope of equation :- The slope-intercept form of a line is a way of writing the equation of a line so that the slope of the line and the y-intercept are easily identifiable. The slope is the steepness of the line, and the y-intercept is the place the line crosses the y-axis.

If the domain of <span>y = 2x - 2 is {1, 2, 3}, then the range has only three values:
2(1)-2=0
2(2)-2=2
2(3)-2=4
The range is {0,2,4}.</span>
Answer:
(x - 4)×(x + 4)
Step-by-step explanation:
(x - 4)×(x + 4) = x^2 - 16
First we need to multiply inside the parenthesis one by one
Multiply x with (x + 4) and the result will be x^2 + 4x
Then multiply -4 with (x + 4) and result will be -4x - 16 we then add both of the result together by adding like terms
x^2 + 4x - 4x - 16 = x^2 - 16 (-4x eliminated 4x) therefore the answer to factorised form of x^2 - 16 is (x - 4)×(x + 4)
