Answer:
If the slopes are different, there is one solution.
If the slopes the same but the y intercepts different, there is no solution.
If the slopes and y intercepts are the same, there are infinitely many solutions.
2x + y = 4
2y = 6 - 2x
Solve for y on both
y = 4 - 2x
y = 3 - x
They are both different, so there is one solution
Step-by-step explanation:
Answer:
Step-by-step explanation:
A linear function has the following format:
In which a is the slope(rate of change) and b is the y-intercept, that is, the value of y when x = 0.
Rate of change of 3
This means that
So
A solution at (6, 12).
This means that when x = 6, y = 12. So
The linear function is:
The value of 7 is 7 because it is in the ones place
