Question

Fill in the missing numbers to complete the linear equation that gives the rule for this table.

x y
0 83
1 67
2 51
3 35


y =|_| x + |_| 

Answer 1

Erin,

 

The table is a list of x,y pairs. You should plot them on a graph (a sketch will do). The result should be a straight line that crosses the y-axis at 83, then slopes downward at a rate of -16. The equation, y=mx + b, is the standard equation for a straight line, where m is the slope of the line, and b is the y-intercept. The values of m and b can be determined directly from the values in the table.
