Answer:
y+1=3(x-4)
Step-by-step explanation:
Hi there!
We are given a slope of 3 and a point (4,-1).
We need to find the equation of the line in point-slope form
Point-slope form is given as y-y1=m(x-x1), where m is the slope, and (x1,y1) is a point
We have all of the needed information to substitute into the formula
First, let's label the values of everything to avoid any confusion
m=3
x1=4
y1=-1
now substitute into the formula *remember, the formula has SUBTRACTION, and we have a NEGATIVE number, so we'll end up subtracting a negative*
y--1=3(x-4)
simplify
y+1=3(x-4)
That's it!
Hope this helps :)
I think the answer should be 25 because if you multiply 2.5 by 10. Technically it means moves 10 to the right.
Answer:
for 7 its r and u and r and s. and for 8 its all.

Answer:
0.01125 foot-candles
Step-by-step explanation:
According to the data, intensity of light measured in foot-candles varies inversely with the square of the distance from the light source
Therefore,
α 1/
= k/
where,
'k' is the constant
'd' is the distance from bulb
' ' is intensity of a light bulb
When,
d= 3meters
= 0.08foot-candles
k= .
k= 0.08 x 3² => 0.08 x 9
k= 0.72
Next is to determine the intensity level at 8 meters.
= k/
= 0.72/ 8²
= 0.01125 foot-candles
Therefore, the intensity level at 8 meters is 0.01125 foot-candles
Answer:
y = - 3x + 3
Step-by-step explanation:
Assuming you require the equation of the line
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - 3 and c = 3, hence
y = - 3x + 3 ← equation of line
