Equation of required line is:
Step-by-step explanation:
We need to write an equation of a line that is perpendicular to y = -5x + 2 and passes through (10,8).
The standard form of slope-point form is:
Where m is the slope and b is the y-intercept
Comparing the given equation y = -5x + 2 with standard form:
The slope m = -5
Since the lines are perpendicular so, the slope of required line will be -1/m
So, slope =m = 1/5
Now we need to find b (y-intercept)
We are given the point (10,8) and slope = 1/5
Putting values in formula:
So, value of b=6
So, Equation of required line is:

Answer: x=114
Step-by-step explanation:
To solve for x, we want to isolate x.
[multiply both sides by 5]
[add both sides by 1.8]
[divide both sides by 0.2]
Now, we know that x=114.
