The equation of a line is given by y = mx + c; where m is the slope.
The given equation is 9 - x = 2y
y = -1/2 x + 9/2
Therefore, the slope is -1/2 and the y-intercept is 9/2.
Congruent since all angles are equivalent to each other.
Hello!
The equation can be written as seen below. You only need a y-intercept and slope to write the equation.
y=-2x+3 (it intercepts at a y-value of 3).
I hope this helps!
