What happens when the line y = x is changed to y = x+2.

the slope increases

the line shifts up 2 units

the line shifts down 2 units

the line is reflected around the y-axis

y = x means that the line is going 1 value of x for every 1 value of y.

The intersection would be at the (0,0).

However, y = x+2 would have a intersection at (0,2) when y-axis have the value 2. The slope doesn't increase, because the derivative of both slopes gives us y = 1.

Therefore, the line shifts up 2 units.

Hope you understood!

Good luck ;)

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
