| To find the coordinates of the points of intersection of the graph of the function y = 3x – 6 (linear function) with the coordinate axes, we must solve two linear equations.
Let’s start by finding the OX intercept, where y = 0.
We substitute functions into the equation and solve the equation.
3x – 6 = 0;
3x = 6;
x = 6: 3;
x = 2.
The point of intersection with the OX axis has coordinates (2; 0).
Now let’s find the point of intersection with the OY axis, where x = 0;
y = 3 * 0 – 6 = -6;
So, the point of intersection with the OY axis has coordinates (0; -6).
