question a)
y = x - 2
the easiest way to plot a line is by locating two points and joining them
our first point is at x=0 , therefore y = 0 - 2 = -2
1st point (0, -2)
our second point is the opposite, so it's at y = 0 , therefore 0 = x - 2 ; then x = 2
2nd point (2, 0)
so this is the plot for question a)q
question b)
y = -3/2 x
same methodology here. Let's find two points
1st point when x=0 , therefore y = -3/2*0 = 0
1st point is (0,0)
the second point can be when x = 2 , then y = -3/2 *2 = -3
2nd point is (2, -3)
so, this is the second plot:
question c )
x = -1.5
In this case, we only have to make a vertical line that passes through x = -1.5
as it follows
question d)
y = -2.5
similar to the previous case, but now we will make a horizontal line that passes through y = -2.5
as it follows:
