How would the graph of the relation y=3x-2 change if the 3 and -2 were both doubled? 

The graph would be 
a) steeper and have a lower y-intercept
b) steeper and have a higher y-intercept
c) less steep and have a lower y-intercept 
d) less steep and have a higher y-intercept

Sagot :

AL2006
y = 3x - 2

-- The ' 3 ' is the slope. If you double it to ' 6 ', the line is steeper.

-- The ' -2 ' is the y-intercept. If you double it to ' -4 ', the line crosses the y-axis lower.

Choice (a) says that . . . "... steeper, and lower y-intercept".
