Answer:
2 and - [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the gradient and c the y- intercept )
f(x) = 2x - 1 ← is in slope- intercept form
with gradient m = 2
• Parallel lines have equal gradients , then
the gradient of a parallel line is also 2
given a line with gradient m then the gradient of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{2}[/tex]
