| In order to find the coordinates of the points of intersection of the graph of the linear equation y = 36x – 18 with the coordinate axes, we will have to solve two linear equations.
In order to find the point of intersection with the OX axis, we must substitute y = 0 into the given equation of the straight line and solve the resulting equation of the system.
0 = 36x – 18;
We solve the resulting equation:
-36x = -18;
x = -18: (-36);
x = 0.5.
(0.5; 0).
We are looking for the point of intersection with the OY axis – x = 0.
y = 36 * 0 – 18;
y = 0-18;
y = -18.
(0; -18).
Answer: (0.5; 0) and (0; -18).
