Answer:
1
Step-by-step explanation:
x+y=-9
y=-x-9
So slope of original line is -1.
The line perpendicular to the original line is -1/-1 = 1
Answer:
Q2: slope = -½
Q3: slope = 1
Step-by-step explanation:
If the equation of the line is in the form y = mx+b, then m is the slope of the line and b is the y-intercept (the point where the line crosses the x-axis).
y = -½x, so the slope of the line is -½
y = x+15, so the slope of the line is 1
