<u>Answer:
</u>
The equation in slope intercept form for (5,9) and (6,8) is y = 3x-10
<u>Solution:
</u>
Given that (5,9) and (6,8)
Here, 
We know the slope of an equation is given by y = mx+c
To find the value of m, we use the below given formula

Substituting the values we get,


m = 3
Putting the value of m in the slope intercept form we get,
y = 3x+c
To find the value of c, we substitute the value of x and y from any two given point. Let’s take x = 5 and y = 5
5 = 3(5) + c
5 = 15 +c
5-15 = c
c = -10
Therefore the slope intercept equation becomes y = 3x -10
Hence, option D 4: x=-1.34 is correct
Further explanation:
In order to solve an equation in one varible we have to isolate the variable on one side of the equations
Given equation is:

Hence, option D: x=-1.34 is correct
