| 1. In order to find the intersection points of the graphs of functions, we equate the right-hand sides of the equalities, we obtain
-14x + 32 = 26x – 8;
-14x – 26x = -8 – 32;
-40x = -40;
x = -40: (-40);
x = 1.
2. Find the value of y, for this value x = 1 we substitute in one of the formulas of the graphs of functions, we have:
y = -14x + 32 = -14 * 1 + 32 = -14 + 32 = 18.
Answer: the intersection point of the function graphs has coordinates (1; 18).
