August 6, 2021 | education
| y = 4x – 4 is a linear function, that is, a straight line, it intersects the x and y axes once.
1) When crossing the x-axis, the value of the ordinate y is 0, substitute zero for the letter y and find the value of x.
0 = 4x – 4;
-4x = -4;
x = 1.
The point of intersection with the x-axis (1; 0).
2) When crossing the y-axis, the value of the abscissa x is equal to zero, substitute zero for the letter x and find the value of y.
y = 4 * 0 – 4;
y = -4.
The point of intersection with the y-axis (0; -4).
