y=-3X the line would cross the y-axis at (0,0)
A line that followed y = 0 would be exactly the same as the line of the x axis.
The slope or gradient is the same and would run parallel but the intercept on the y axis would be at -1
y=-2.5 is parallel to the x axis. The equation of the x axis is y=0
-15
y=-2 is parallel to the x-axis and perpendicular to the y-axis.
Y is undefined because the line x=1 never crosses the y axis.
5
You would draw a straight horizontal line through the 5 on the y axis.
Y axis equals altitude and X axis is distance.
Yes and it will be a straight line intercepting y at -1 and parallel to the x axis
You get a straight line (parallel to the x-axis) that passes through only the y-axis, and it crosses the y-axis at (0,3)
