Question

Consider the following equations:

y = X-2
y = 2x-2
y = x-2
y = -2

Discuss the similarities and difference in the graphs of these equations. (Use a graphing calculator if needed.)

a. Same slopes; different y-intercepts
b. Same slopes; same y-intercepts
c. d. different slopes; same y-intercepts
d. different slopes, different y-intercepts

Please select the best answer from the choices provided​

Answer 1

c. d. different slopes; same y-intercept

for all the equations, when x = 0, y = -2

apart from the last equation which has no x-intercept.

They have different slopes i.e

y=x-2 has a slope of 1

y=2x-2 has a slope of 2

y=x-2 has a slope of 1

y=-2 has no slope

Answer 2

c number is the correct one i think
