Find the value of x and the value of y for which (x, 14) and (18, y) are points on the graph. y = 0.5x+12 .

The values of x and y are 4 and 21

Step-by-step explanation:

Given: The coordinate points (x, 14) and (18, y) are on the graph y = 0.5 x+12.

An ordered pair (x, y) represents a position of a point on a coordinate graph, where x is the number on the x-axis, and y is the number on the y-axis. The numbers x and y in the ordered pair (x, y) are called coordinates.

we will substitute the points (x, 14) and (18,y)  on the graph y =0.5 x+12 to solve for x and y, then we have:

   and  

now;

14 = 0.5x+ 12

⇒ 0.5x= 14-12 =2 or

Therefore, the point (4, 14)

Now, solve for y:

or

= 21

⇒ the point (18, 21)

Therefore, the values of x and y are 4 and 21

x=30

step-by-step explanation:

both equations and proportions are better.
