Hello there!
A positive slope is represented in a linear equation by a positive coefficient behind the x term. A positive slope means that the graph is on an increasing interval as x approaches +∞. In a more simple way, a positive slope means that the graph is going up from left to right.
A negative slope is represented in a linear equation by a negative coefficient behind the x term. A negative slope means that the graph is on a decreasing interval as x approaches +∞. In a more simple way, a negative slope means that the graph is going down from left to right.
The x intercept(s) of a graph are where the graph touches the x-axis. These are also known as the zero(s) OR solution(s) of the function.
The y intercept(s) of a graph are where the graph touches the y-axis.
I hope this helps!
Best wishes:)
2200(.15)=330.00
2200+330=2530
2530(.07)=177.10
2530+177.30=2707.10
Solve for the first variable in one of the equations, then substitute the result into the other equation.
Point Form:
(2, -1)
Equation Form:
x= 2, y= -1
Terry should buy the half liters because 6 will be $14.34 and if he got the millimeters then it would cost him $20.28
