Answer: 
Step-by-step explanation:
The equation of the line in Slope-intercept form is:

Where "m" is the slope of the line and "b" is the y-intercept.
Find the slope with this formula:

Given the points (-10,-7) (3,-7), substitute values into the formula. Then:

Substitute the slope and any point into
and solve for "b":

Then, substituting "m" and "b" into the equation
, you get that the equation of this line is:


Answer:
Step-by-step explanation:
a² + b² = c²
3.6² + b² = 7.4²
b² = 7.4² - 3.6² = 41.8
b = √41.8
Answer:
11 cm
Step-by-step explanation:
1m = 100cm
By examining the graph carefully, we can see that the record in 1985 is 2.4 m. In 1970 it was slightly under 2.3 m. For it to be 15cm it would have to be 2.25m. For it to be 9 cm it would the record would have been above 2.3m.
