slope = -2 and y-intercept is +1.
x-intercept is $\frac{1}{2}$ $1/2$

You have them immediately because the equation is in standard form $y = m x + c$ $y =mx+ c$ where m is the slope and c is the y-intercept!

Could not be simpler..., just recognise what it is and voila!

YOu can also fine the x-intecept by making y = 0.

$0 = - 2 x + 1 \Rightarrow 2 x = 1 \Rightarrow x = \frac{1}{2}$ $0 = -2x + 1 rArr 2x = 1 rArr x = 1/2$

What is the slope and intercept of y=−2x+1y=-2x + 1?
