Let, the points be A (8, −4) and B (1, −5). The slope of line AB exists 1/7.
<h3>How to estimate the slope of line AB?</h3>Utilize the slope formula to estimate the slope of a line provided the coordinates of two points on the line.
The slope formula exists , or the difference in the y values over the difference in the x values. The coordinates of the first point symbolize
and
. The coordinates of the second points exist
The slope of the line exists the ratio of the rise to the run, or rise separated by the run.
The Line, AB contains points A (8, −4) and B (1, −5).
Substitute the value of points in the equation then we get
m = (-5-(-4))/(1 - 8)
Simplifying the above equation, we get
m = (-5+4)/(1 - 8)
m = (-1)/(-7)
m = 1/7
Therefore, the slope of line AB exists 1/7.

Answer:
(4, 0) and (6, 0)
Step-by-step explanation:
The function that we have is:
This is the function of a <u>parabola.</u>
to find the points where the function crosses the x-axis, we need to find the values of x for which g(x) (which is the value of the y-axis) is equal to zero.
so we need for the function to be crossing the x-axis.
Thus our equation becomes:
and we can solve this equation with the quadratic formula or by factoring.
I will sove by factoring:
To factor this type of equations we need to find 2 number that satisfy the following:
- when multiplied result in +24 (the independent number of the equation)
- and when added or substracted result in -10 (the coefficient of the x in the equation)
In this case those 2 number are: -6 and -4 because:
(-6)(-4)=+24
-6 - 4 = -10
Thus we arrange our factored equation as follows:
from through factoring we get:
and because of the <u>zero factor property</u> (if two things when multiplied result in zero one of them or both must be zero), thus our x values are:
and
thus, our points are those with and y coordinate of 0 and an x coordinate of 6 and 4:
(4,0) and (6,0)
