Answer:
(y equals start fraction two over three end fraction x)
Step-by-step explanation:
Lest's organize the table values of our function first:
x y
-6 -4
-3 -2
0 0
3 2
The simplest kind of of function is a linear function of the form where
is the slope and
is the y-intercept. Let's us check if our function is a linear one finding its equation and checking that all points are in the line.
The first step to find a linear equation is find the slope of the line; to do it, we are using the slope formula:
where
is the slope of the line
are the coordinates of the first point
are the coordinates of the second point
We know from our table that the first and second points are (-6, -4) and (-3, -2) respectively, so ,
,
, and
.
Replacing values:
Now that we have the slope of our line we can use the point slope formula to complete our linear function:
where
is the slope
are the coordinates of the first point
Replacing values:
Now, to check if our function is valid, we can either check if each point satisfies the rule , or we can graph it and check if each lies is in the graph.
Let's check both:
We already know that points (-6, -4) and (-3, -2) satisfy the rule (after all, those were the point we used to came out with the rule in the first place), so we just need to check the points (0, 0) and (3, 2)
- For (0, 0):
The point satisfies the rule.
- For (3, 2):
The point satisfies the rule.
Since all the points of our table satisfies the rule , we can conclude that the rule describing the function shown is
.
The point such that the coordinate is 5;3 is (14, 0)
<h3>Midpoint of coordinates using ratio</h3>The formula for finding the midpoint of a line in the ratio m:n is expressed as:
M(x, y) = {(mx₁+nx₂)/2, (my₁+ny₂)/2,}
Given the coordinate of G and D on the line as G(5, 0) and D(1,0)
Since there is no y-axis, hence;
x = 5(5)+1(3)/2
x = 25+3/2
x = 28/2
x =14
Hence the point such that the ratio is 5;3 is (14, 0)
