We will use the formula to calculate the slope of the line passing through the points 38 and -2 10. X1 x2 are the coordinates of x-axis and y1 y2 are the coordinates of y-axis. Set up the slope formula.
How to find slope.
M change in ychange in x. Simplify the fraction to get the slope of -25. A more general way is to use the formula y2 - y1 x2 - x1 where y2 is a result of whatever expression you started with so here 100 dollars for 8 hours which means you could say 100 is one output. The slope will be.
