Step-by-step explanation:
Using the distibutive property all you have to do is have the number on the of the parenthesis multiply itself to each component in your parenthesis.
−3 ( −3b + 5 ) + 9 ( 7b + 5
= 6(12b+5)
Rate of change of line that passes through the given points is 1
Step-by-step explanation:
The ratio of vertical and horiontal changes is called the rate of change of a line. It is called slope which is denoted by m.
The formula for slope when (x1,y1) and (x2,y2) are the points on line is given by:

Given
(x1,y1) = (-6,-6)
(x2,y2) = (-2,-2)
Putting the values in the formula

Rate of change of line that passes through the given points is 1
