Kevin plotted a linear equation on a graph with 18 as the y-intercept. Which of the following could be the equation plotted by Kevin?

y-intercept is a point where the graph of a function or relation intersects with the y-axis of the coordinate system.

OR

y-intercept is a point where x = 0

1 / 2 y = 9 x + 5 Multiply both sides by 2

y = 18 x + 10

for x = 0

y = 18 * 0 + 10 = 0 + 10 = 10

y-intercept = 10

3 x = 6 - 1 / 3 y Multiply both sides by 3

9 x = 18 - y Add y to both sides

9 x + y = 18 - y + y

9 x + y = 18 Subtract 9 x to both sides

9 x + y - 9 x = 18 - 9 x

y = - 9 x + 18

for x = 0

y = - 9 * 0 + 18 = 0 + 18 = 18

y-intercept = 18

Answer:

3x = 6 - 1 / 3 y

1/2y = 9x + 5

3x = 6 - 1/3y

That is the correct answer. How did you come up with it?

To determine the possible equations plotted by Kevin, we need to consider the form of a linear equation: y = mx + b.

Given that the y-intercept is 18, this means that the equation intersects the y-axis at the point (0, 18). The value of b is the y-coordinate of this point.

Now, we can consider the possible values for m, the slope of the line. Since we don't have any information about the slope, it can be any real number.

Therefore, the equation plotted by Kevin could be y = mx + 18, where m is any real number.
