It need to be more clear for me to read
Answer:
x=5
Step-by-step explanation:
f(x) = 7
We want to find the x value so that y = 7
Looking at the graph, the x value when y = 7 is x=5
f(5) =7
For the horizontal segment, the value of the ordinate will not change. Then the second point will be (x, 3.5).
<h3>What is coordinate geometry?</h3>
Coordinate geometry is the study of geometry using the points in space. Using this, it is possible to find the distance between the points, the dividing line is m:n ratio, finding the mid-point of the line, etc.
The point is given as (3, 3.5).
Then name a second point so that the two points form a horizontal segment.
For the horizontal segment, the value of the ordinate will not change.
Let x be the abscissa.
Then the point will be given as (x, 3.5).
More about the coordinate geometry link is given below.
