Answer:

Answer: y = 2x + 8

Step-by-step explanation:

• General equation of a line:

$\hookrightarrow \: { \rm{y = mx + b}}$

m is slope / gradient
b is y-intercept.

[ for parallel lines, slopes are the same ]

• m is 2

${ \rm{y = 2x + b}}$

for point (-2, 4)

${ \rm{4 = (2 \times - 2) + b}} \\ \\ { \rm{4 = - 4 + b}} \\ \\ { \rm{b = 8}}$

• therefore, equation is:

${ \boxed{ \rm{y = 2x + 8}}}$

Answer:

Part B: is -60 divided by -10

Part C: is The number of increments is positive.

Part D: is -1 times 60 / -1 times 10

Part E: is Any number divided by itself is 1. In the expression -1 times 60, the -1s in the numerator and the denominator cancel each other out to give the result 60/10, or 6

Part F: is There are 6 increments of -10 feet in -60 feet.

Part G is: copy and paste -10 feet 6 times

Part H: is -60 / 4 increments

Part I: is there is one negative number in the expression, so the solution will be negative. There isn't a -1 in the denominator to cancel out the -1 in the numerator.

Part J: is -60 /4 =-15 Alex’s elevation change in each increment was -15 feet.

Step-by-Step Explaination: I did the test.
