• $y=0$

• $y=x$

• $x=0$

• $y=-x$

Answer explanation

x = 0

is the equation of the y-axis

• $y=x$

• $x=1$

• $x=-1$

• $x=0$

Answer explanation

Equations for oblique lines always have

BOTH x

AND y in them.

Here, the slope of the line is +1

• $x=\frac{3}{2}$

• $y=\frac{3}{2}$

• $x=-\frac{3}{2}$

• $y=-\frac{3}{2}$

Answer explanation

$-1.5\ =\ -\frac{3}{2}$

• $x=2$

• $y=x$

• $x=0$

• $y=2$

• $y\ =\frac{1}{2}$

• $x=\frac{1}{2}$

• $y=-\frac{1}{2}$

• $x=-\frac{1}{2}$

• $x=0$

• $y=0$

• $y=x$

• $y=-x$

Answer explanation

y = 0

is the equation of the x-axis

• $y=\frac{5}{2}$

• $x=\frac{5}{2}$

• $y=-\frac{7}{2}$

• $x=-\frac{7}{2}$

Answer explanation

$-3.5\ =\ -\frac{7}{2}$

• $x=\frac{1}{2}$

• $y=\frac{1}{2}$

• $y=\frac{1}{2}x$

• $x=0$

• $y=\frac{11}{2}$

• $x=-\frac{11}{2}$

• $y=-\frac{11}{2}$

• $x=\frac{11}{2}$

Answer explanation

$-5.5\ =\ -\frac{11}{2}$

• $x=\frac{15}{2}$

• $y=\frac{15}{2}$

• $x=-\frac{15}{2}$

• $y=-\frac{15}{2}$

Answer explanation

$7.5\ =\ \frac{15}{2}$
