Find the coordinates of the points of intersection with the coordinate axes of the graph of the function y = 7x + 7.

The coordinate axes are the abscissa axis (OX) and the ordinate axis (OY).
1) When crossing the abscissa axis y = 0, then:
If y = 0, then y = 7x +7;
0 = 7x +7;
-7x = 7;
x = 7: (-7);
x = -1;
This means that the straight line y = 7x + 7 intersects the abscissa at the point (-1; 0);
2) When intersecting with the y-axis x = 0, then:
If x = 0, then y = 7x +7 = 7 * 0 +7 = 0 + 7 = 7;
This means that the straight line y = 7x + 7 intersects the ordinate at the point (0; 7);
Answer: (-1; 0) and (0; 7);
