Answer:
2.4
Step-by-step explanation:
Okay so first what you would do is find the common difference we can find this by doing 5/3 which is 1.66666666667 (rounded to 1.7)
Then what we do is 4 divided by 1.66666666667 which is 2.4
I hope this helps you

9 (x-18)=3x-18
9x-9.18=3x-18
9x-3x=9.18-18

Answer:
d= -5
Step-by-step explanation:
The slope of a line is found by finding the ratio of change is y values to change is x values

The points on the line have coordinates at: (-1,7) (-3,d)
where ;

Applying the formula with values as;

The value of d = -5
The coordinates of the points (-1,7) (-3,-5)
Given a table, with an input (x) and output (y) , you could actually use the slope formula to get the rate of change because slope is the same thing as rate of change. If you recall, the slope formula is (y2-y1)÷(x2-x1)
Just pick two points from the chart and plug them in and that is your rate of change
