Find the slope of the line that passes through (-66, -21) and (-67, 20)

1 answer:

5 0

The straight line is given by the equation
y=kx+b
We substitute coordinates of points
-21=-66k+b (1)
2=-67k+b (2)
We give a system of equations
Solution of this system:
(1) b=66k-21
(2) 20=-67k+66k-21
20=-k-21
k=-21-20
k=-41
b=-41*66-21=-2727
y=-41x-2727

1/6m=5/8<br> i can't slove this question<br> 8th Grade Math

murzikaleks [220]

we are given

$\frac{1}{6} m=\frac{5}{8}$

Since, we have to solve for m

so, we will try to isolate m on anyone side

so, firstly , we will get rid of 1/6

so, we can multiply both sides by 6

$6*\frac{1}{6} m=6*\frac{5}{8}$

$m=6*\frac{5}{8}$

now, we can simplify right side

$m=3*\frac{5}{4}$

now, we can multiply them

and we get

$m=\frac{15}{4}$ ...........Answer
