Answer:
b = 
Step-by-step explanation:
Given
y =
b + 10
Multiply through by 8 to clear the fraction
8y = 5b + 80 ( subtract 80 from both sides )
8y - 80 = 5b ( divide both sides by 5 )
= b
By definition
... sec(θ) = 1/cos(θ) . . . . trig identity
... sec(θ) = 1/(9/10) . . . . substitute the given value, then simplify to ...
... sec(θ) = 10/9
So the equation is parallel and the slope will be 2
y=2x+b
sub in(5,4) for x and y to find b
4=2(5)+b
4-10=b
b=-6
therefore the equation is y=2x-6
You can't simplify 23/67 into a whole number since it is less than one, but you can change it into a decimal by dividing the two numbers.
