Find the slope of the line joining the points ( -2, 5 ) and (8, -7 )
A line with slope passes through the points ( 5, 2 ) and (9, y ) Find y
What is the midpoint of the segment between ( -4, 9 ) and ( 28, -29 )?
Find the slope of the line y = 7x + 2.
Find the slope of the line 5x + 2y + 9 = 0.
Find the area of the region bounded by the y-axis, the line y = 6, and the line y = 1/2x.
Not very good English, this is not homework, just a introduct to slope in mathematicallics
Thank!
Find the slope of the line joining the points ( -2, 5 ) and (8, -7 )
Slope = [ subtract the y coordinates in any order ]
___________________________________
[ subtract the x coordinates in the same order]
So we have
[ -7 - 5] - 12 - 6
_______ = _____ = ____ = the slope
[ 8 - - 2] 10 5
What is the midpoint of the segment between ( -4, 9 ) and ( 28, -29 )?
Midpoint
( add x coordinates and divide by 2, add y coordinates and divide by 2 )
So .....
[ (-4 + 28) / 2 , ( 9 + -29) / 2 ] =
[ 24 / 2 , -20 / 2 ] =
[ 12, -10 ]
Find the slope of the line y = 7x + 2.
This is easy, Android.....
In the form
y = mx + b
The slope is just m
So
y = 7x + 2
So...the slope is 7
