Need help for question 8 and 9. I need the equation that’s passes through the points!

Step-by-step explanation:

Question 8

Let the equation of a line passing through two points and is given by,

y = mx + b

Here, m = slope and y-intercept = b

Since, m =

For two points (1, 4) and (5, 8),

m =

m = 1

Equation will be,

y = (1)x + b

y = x + b

Since, this line passes through (1, 4),

4 = 1 + b

b = 3

Therefore, equation of the line will be,

y = x + 3

Question 9

Let the equation is y = mx + b

m =

For two points (2, 10) and (6, 4)

m =

m =

By substituting the value of 'm' in the equation,

y =

Since, this line passes through (2, 10)

10 =

b = 10 + 2

b = 12

Therefore, equation of the line will be,

answer: haha (: i’ll go see what it is

step-by-step explanation:

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
