CH. 3. 1 SOLVING SYSTEMS USING GRAPHS EQ: How can I solve a system using tables and graphs? I will solve a system using tables and graphs. Linear Systems

Bell Work Evaluate 1. 9 t + 6(2 v-t) -7 v; t=1, v=5 Write in slope-intercept form 2. y-5 x = 16 Graph each equation 3. 12+2 y = 3 x EQ: How can I solve a system using tables and graphs? I will solve a system using tables and graphs.

Solving Systems using graphs Linear systems of two equations can be analyzed using the nature of the solutions. One solution 2 lines intersect at one point The slopes of the lines are not equal The y-intersects may or may not be equal Infinitely many solutions 2 lines coincide The slopes are equal The y-intersects are equal No solution 2 parallel lines Same slope, different y-intercept EQ: How can I solve a system using tables and graphs? I will solve a system using tables and graphs.
