How many solutions will this system of equations have? y = -3.5x - 3.5 y = -3.5x + 3.5 No solution Infinite solutions One solution Two solutions
A
A is wrong. Add the two equation then you get 2y=-7x y=-7x/2 |dw:1388859192754:dw|
from the graph you can see that for every x values you can get a y value so there are infinetly many solutions
Add the 2 equations 2y = -7x 7x + 2y = 0 We have only 1 equation but we need two. If that is the case then there in NO solution. For any value of x we can find a value of y so in that case there are INFINITE solutions.
I can not be Infinite Solutions...... The slopes of the equations are the same but with different y-intercepts so say u were to graph the equations roughly..... |dw:1388859807248:dw| That is the result....
