first you need to find the slope (m) using y2-y1/x2-x1.
-4-2/4-1= -6/3=-2
m=-2
then plug into the intercept form formula: y-y1=m(x-x1)
y-2=-2(x-1)

number sof student of the group is 50
Step-by-step explanation:
let the number students be x
total bill is Rs 200
each student will pay =200/x
now 10 students do not have the money
so x - 10 students will pay the bill of Rs 200
according to the problem
=
+ 1
or,
-
= 1
or, 200 (
-
) = 1
or, 200(
) = 1
or, 200 X 10 = x(x-10)
or,
- 10x - 2000 = 0
or,
- 50x +40x - 2000 =0( using middle term factor)
or, (x - 50) (x+40) = 0
x = 50 ( x = -40 for number of students it is not possible)
Answer:
the gradients are the most important features.
Step-by-step explanation:
if the linear functions are parallel with different constants, they won't intercept. If they are parallel with an equal constant, they are the same function. Any linear functions with different gradients will always intercept
