How to solve y=10-4x
I prefer to write this as...
It is now in the format of...
This is the slope-intercept formula for a line on a graph.
Slope is also called rise-over-run, rise/run, the change of y divided by the change of x.
The b represents the value of y when x=0. On a graph, it is the point in which the line crosses the y-axis.
This formula is...
The slope is -4. As the line rises positively 4 units on the y-axis, it moves negatively to the left on the x-axis 1 unit.
When x=0, the value of y is 10, (0,10).
Let's input a few numbers.
The coordinates we now have are...
As the value of y increases 4 units, the value of x decreases by 1 unit.
I hope this helps.
