| x – 0.75y + 2 = 0.
1) To find the point of intersection with the x-axis, you need to express x from the equation and substitute y = 0.
Let us express x:
x = 0.75y – 2.
Substitute y = 0:
x = 0.75 * 0 – 2;
x = -2.
2) To find the y-intercept, express y from the equation and substitute x = 0.
Let us express y:
0.75y = x + 2;
y = (x + 2) / 0.75.
Substitute x = 0:
y = (0 + 2) / 0.75;
y = 2 / 0.75.
When dividing, an infinite decimal fraction is obtained, so we write it as an ordinary fraction:
y = 8/3.
Answer: the point of intersection with the x-axis: (-2; 0), with the y-axis: (0; 8/3).
