If a is directly proportional to b, we have the relationship to be:
When a = 25, b = 35. Therefore, we can calculate the value of k as follows:
Therefore, the relationship is given to be:
When a = 40, we can calculate the value of b to be:
The value of b is 56.
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)
