The equation of the line that passes through the point (-4 , 3) with slope ₋2 is:
y = ₋2x ₋ 5
Given the points are (₋4 , ₋3) and (4 , 1)
The gradient of the line through the points' locations (x₁ , y₁) and (x₂ , y₂) is: y₂ ₋ y₁/x₂ ₋ x₁
Substitute the given points in the above formula:
=1 ₋(₋3)/4 ₋ (₋4)
=4/8
=1/2
If the product of the slopes of two perpendicular lines is -1, then the slope of the perpendicular line is ₋1/1/2 = ₋2
Therefore the line that passes through the point (-4 , 3) with slope ₋2 has equation:
y ₋ 3 = ₋2(x ₊ 4)
y = ₋2x ₋ 8 ₊ 3
y = ₋2x ₋ 5
Hence we get the expression as y = ₋2x ₋ 5

Answer:
f(1/3)=3 try that its probably right
Answer:
C. 2 x (6 + 8)
Step-by-step explanation:
If you are trying to add before you multiply, you have to put a parantheses. This way, you would add 6 + 8 first, then multiply it by 2.
Remember
and
if
where x=x then m=n
so
so
m+n=-6
so test the options
first one works
2nd ones doesn't
3rd one doesn't
4th one doesnt'
answer is first option, m=3 and n=-9
A)
p-5w=8L + 5w - 5w
p -5w=8L
(p- 5w)/8 = 8L/8
(p- 5w)/8 = L
