Answer:
From the General Equation of a straight line
Y=Mx + c
where M = Slope of the line
c= Intercept on Y axis
y=-4.2x-80
Comparing with the Eqn of a straight line
Slope = -4.2
From the Options the answers are in Fractions
You can easily convert this figure to fraction by Moving the decimal to the back once and then divide by 10
Then we have -42/10
Reducing Further
you have = -21/5.
Option D✅
I think you would divide each by 2 and get 1 over 1 which would be 1 squared over 1 (negative) cubed
Hope this helps!
Answer:
Option C. linear: slope = -5, y-intercept = 50
Step-by-step explanation:
Let
b ----> is the automatic decrease on the gift card balance
m ----> is the number of months beyond two years
we know that
The equation of the line into slope intercept form is equal to
where
m is the slope
b is the y-intercept
In this problem the linear equation that represent this situation is
---> equation of the line into slope intercept form
so
The slope is -5
The y-intercept is 50
