Answer: the answer is 1
Step-by-step explanation:
First we need to find slope of given line −4x+3y=−2
So convert it into slope intercept form y=mx+b
−4x+3y=−2
3y=4x−2
y=4/3x−2/3
Comparing above equation with y=mx+b gives m=4/3
Hence slope of given line is 4/3.
<em>We need slope of perpendicular line which is always "negative reciprocal of given slope"</em>.
Negative of 4/3 is -4/3.
taking reciprocal gives -3/4
Hence slope of required perpendicular line is m=-3/4
-------
Now we need to find y-intercept of −7x−7y=6
y-intercept is always the y-value when x=0 so let's plug x=0 into −7x−7y=6
−7(0)−7y=6
0−7y=6
−7y=6
y=-6/7
y-intercept is also called "b" in y=mx+b
hence b=-6/7
-----
Now we know that slope of perpendicular line is m=-3/4 and y-intercept b=-6/7
so plug both into formula y=mx+b
We get Final answer is

Answer: A.
Step-by-step explanation: First you must think about how many miles is 9 kilometers. How many miles in 9 kilometers is 5.59234. And A is the closest to the numbers of miles Tristan rode his bike. The other questions would be wrong. It isn't the exact one because it's the closest, not exact. Hope that helps :).
Nice description. But you've omitted or overlooked the instructions. I'm assuming that you want to find the equation of this linear function.
13-(-2) 15 -5
The slope of this line is m = ----------- = --------- = ----
-4 -2 -6 2
Use the point-slope form of the equation of a straight line:
y-(-2) = (-5/2)(x-2), or y = -2 - (5/2)x + 5, or y = (-5/2)x + 3.
