Answer:
-5
Step-by-step explanation:
y- 1/5x = 7
y= 1/5x +7
So, the slope of the line is 1/5
Perpendicular slopes are always the reciprocal with an inverse sign.
So, -5
Answer:
Step-by-step explanation:
I assume that XY is midsegment of a triangle, then MO = 2 XY
9x - 20 = 2( 3x - 4 )
9x - 20 = 6x - 8
3x = 12
x = 4
MO = 9(4) - 20 = 16 units
Answer: y = (-2/5)x - 7
This is the same as writing 
======================================================
Explanation:
Any linear equation is of the form y = mx+b, known as slope-intercept form
m = slope
b = y intercept
We'll replace m with -2/5 and replace b with -7 to get y = (-2/5)x + (-7) which simplifies to y = (-2/5)x - 7
