Answer:
-3/2
Step-by-step explanation:
the slope of a line is expressed as ratio y/x showing how many units y changes, when x changes a certain number of units.
so, going from A to B, x changes 4 units (from -3 to +1), and y changes 6 units (down, from +3 to -3). that makes the y change negative.
so, the slope is
-6/4 = -3/2
Step-by-step explanation:
4 + n + 7m
constants are just the numbers with no variables (letters)
so the constant is 4
coefficients are numbers multiplied by variables (letters)
so the coefficients are : 7 and 1
the error sarah made is forgetting the coefficient of n......because even if it is not written, n is the same as 1n....so basically, there is a coefficient for EVERY variable, even if its not written.
D is the answer because 1 and 9
A would be 1 as b would be -4
