Answer:
Step-by-step explanation:
Knowing that slope-intercept form is y=mx+b. mx being the slope and b being the y-intercept.
First, you will first find the slope, which is (y2-y1)/(x2-x1):
5-(-1) / 1-(-1) = Which becomes 6/2.
6/2 = 3. So the slope is 3x
Now when you plot the dots on a graph with a slope of 3 (basically 3/1 knowing that slope is rise over run) you will see that the point that intercepts on the y-axis is 2. So your y-intercept, or b in this equation, is 2.
I believe the slope-intercept form: y=3x+2
It is in the hundreths place if that answers your question.
Answer:
A. x + y = 5
Step-by-step explanation:
The slope of the equation is equal for parallel lines,
; Slope = (-1)
;Use the formula
(y - y(coordinate of the given point)) = slope × [(x - x(coordinate of the given point)]
; y - 1 = (-1)(x - 4)
; y - 1 = -x + 4...then move the variable (x) to the left hand side and then move (-1) to the right hand side
; x + y = 4 + 1
; Hence,
; x + y = 5
so you can either do pounds per dollar or dollars per pound:
pounds per dollar : about 0.71 lbs / $
dollars per pound : $1.40 / lb
i hope this helped, based on the question i believe that it is dollars per pound but its good to know both and have a nice day
