Since the slope-intercept form of a line is given by the expression:

Where, m is the slope and b is the y-intercept.
Then, for the function:

The slope is -2 and the y-intercept is (0, 3)
10) 7(2m+3)
11) 3(3r-1)
12) 2p(5q+4)
I don't see the answers, but it would most likely be 59 + x.
Negative Exponent Rule:
this says that negative exponents in the numerator get moved to the denominator and become positive exponents. Negative exponents in the denominator get moved to the numerator and become positive exponents.
Like this||
Volume = length x width x height
Volume = 33 x 29 x 18
= 17,226
Number of whole cubes formed by the defined volume = 17,226/3
= 5742 cubes
