Answer:
(- 1, 5 )
Step-by-step explanation:
Under a reflection in the x- axis
a point (x, y ) → (x, - y ), thus
(- 1, - 5 ) → (- 1, 5 )
Answer: slope, m = -7/3
Step-by-step explanation:
The equation of the line is
7x+3y=15.
To find the slope,
We will consider the standard slope intercept equation also known as the equation of a straight line,
y = mx + c
Where m = slope( change in y values divided by change in x values)
c = the y intercept. This is the point where the straight line cuts across the y axis
Looking at the given equation, 7x+3y=15,
We would need to rearrange it and make y the subject of the formula. It becomes
3y = 15 - 7x
Dividing the right hand side of the equation and left hand side of the equation by 3,
y = -7x/3 + 15. Comparing with the slope intercept equation,
m = -7/3
If 5 pens cost 95 cents, that means that each pen cost 95/5 = 19 cents each. So a dozen will cost:
dozenCost = 12*19 = 228 cents
