Answer 2

Finding the Coordinates of Intersection Points

To find the coordinates of the intersection points between the given functions and the x and y axes, we can set the respective function equal to zero and solve for the variable.

a) For the function y = 1.5x + 18, to find the coordinates of the intersection point with the x-axis, we set y = 0 and solve for x:

0 = 1.5x + 18

Solving this equation, we find:

x = -12

Therefore, the coordinates of the intersection point with the x-axis are (-12, 0).

b) For the function y = -2x + 5, to find the coordinates of the intersection point with the y-axis, we set x = 0 and solve for y:

y = -2(0) + 5

Simplifying this equation, we find:

y = 5

Therefore, the coordinates of the intersection point with the y-axis are (0, 5).

c) For the function y = 4x^2 + 48, to find the coordinates of the intersection point with the x-axis, we set y = 0 and solve for x:

0 = 4x^2 + 48

Simplifying this equation, we find:

x^2 = -12

Since the square of a real number cannot be negative, there are no real solutions to this equation. Therefore, there are no intersection points between the graph of this function and the x-axis.

d) For the function y = x - 9, to find the coordinates of the intersection point with the y-axis, we set x = 0 and solve for y:

y = 0 - 9

Simplifying this equation, we find:

y = -9

Therefore, the coordinates of the intersection point with the y-axis are (0, -9).

In summary, the coordinates of the intersection points are: a) (-12, 0) b) (0, 5) c) No intersection points with the x-axis d) (0, -9)
