"Determining linear function expressions using linear equations of two variables" PPT teaching courseware for linear equations of two variables, 8 pages in total.

Part One Content: Basic Knowledge Key Points

Knowledge point 1: The relationship between linear equations of two variables and linear functions

1. It is known that the coordinates of the intersection of straight line y=3x-3 and y=-3/2x+b are (4/3 "," a), then the system of equations {(- 3x+y+3=0 3x+2y - The solution of 2b=0) is (B)

Use linear equations of two variables to determine linear function expressions PPT, Part 2: Improvement of comprehensive abilities

4. The abscissa of the intersection P of straight line l1:y=x+1 and straight line l2:y=mx+n is 1, then which of the following statements is wrong (C)

A. The coordinates of point P are (1,2)

B. The solution of the system of equations {(y=x+1"," y=mx+n) about x, y is {(x=1"," y=2)

C. In straight line l1, y decreases as x increases.

D. The straight line y=nx+m also passes through point P

Use linear equations of two variables to determine linear function expressions PPT, the third part: Expand and explore breakthroughs

6. We define: linear functions y=ax+b and y=bx+a about x are called a pair of exchange functions. For example, y=3x+4 and y=4x+3 are a pair of exchange functions.

(1)Write the exchange function of the linear function y=-2x+b　y=bx-2　;

(2) When b≠-2, write the abscissa coordinate of the intersection point of the two function graphs in (1) 1;

(3) If the area of ​​the triangle formed by the graph of the two functions and the y-axis in (1) is 3, then b=　4 or -8　.
