Answer:
see explanation
Explanation:
(a)
A horizontal line has equation
y = c ( c is the value of the y- coordinates the line passes through ), then
y = - 3 ← is the equation of a horizontal line
(b)
A vertical line has equation
x = c ( c is the value of the x- coordinates the line passes through ) , then
x = 4 ← is the equation of a vertical line
(c)
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 5x ← is in this form
y + x = 6 ( subtract x from both sides )
y = - x + 6 ← is in this form
then
y = 5x and y + x = 6 ← are sloping lines
(d)
y = x² is a quadratic
the graph of a quadratic is a curve with a maximum / minimum vertex
y = x² ← is not a straight line
