1) Find the abscissa of the intersection point of the graphs of the functions y = 2x – 3 and y = 7 – 3x. To do this, you need to equate the right-hand sides of the equations.
2x – 3 = 7 – 3x;
2x + 3x = 7 + 3;
5x = 10;
x = 10: 5;
x = 2.
2) Find the ordinate of the intersection point of the graphs. To do this, you need to substitute the value of the variable x into any of the equations, for example, into the first one.
y = 2x – 3 = 2 * 2 – 3 = 4 – 3 = 1.
