How do you graph y=−12 using intercepts?
1 Answer
see explanation.
Explanation:
It helps if we can recognise that lines of the form
y=c and x = c where c is a constant, are special cases of the equation of a straight line.y = c is a straight line, parallel to the x-axis passing through all points in the plane with the same y-coordinate.
y=−12 therefore passes through all points whose y- coordinate is−12 This includes the point on the y-axis, the y-intercept whose coordinates are(0,−12) Plotting 3/4 points and drawing a straight line through them gives the graph of
y=−12 For example plot the following set of points.
(−2,−12),(0,−12),(2,−12) and (4,−12)
graph{y-0.001x+1/2=0 [-10, 10, -5, 5]}I mentioned x = c , which is a line parallel to the y-axis, passing through all points in the plane with the same value of x-coordinate.
