Answer:
y = - x + 9
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 2x - 3 ← is in slope- intercept form
with slope m = 2
Given a line with slope m then the slope of a line perpendicular to it is
= - = - , thus
y = - x + c ← is the partial equation
To find c substitute (8, 5) into the partial equation
5 = - 4 + c ⇒ c = 5 + 4 = 9
y = - x + 9 ← equation of line
The length of the last side is 13.416, I am not sure what you need to round your numbers to but you can round it to whatever you teacher wants.

To evaluate an expression in maths, plug in he value of the variable, then simplify the expression following the order of operation.
Assuming we are given the expression, 3x + (2x - 1), and we are required to evaluate the expression, the following shown below is how to evaluate the expression if we are told that x = 1.
- First step is to plug in the value of the variable, x, into the expression:
3(1) + (2(1) - 1)
3 + 2 - 1
- Using the order of operation, simply
4
Therefore, to evaluate an expression in maths, plug in he value of the variable, then simplify the expression following the order of operation.
