Answer:
(y2-y1)/(x2-x1)
Step-by-step explanation:
Using two coordinates, you can just plug in the corresponding (x,y) coordinates and you will get the slope, which is the rate of change over an interval
Answer:
A. y + 6= -2(x - 4)
Step-by-step explanation:
Let A(a , b) be a point of the line
and m be the slope.
The equation of the line in Point-slope form :
y - b = m (x - a).
…………………………
Given :
Slope = -2
A(4 , -6)
Then
Point-slope equation : y + 6= -2(x - 4)
Answer: r= 12.58m
Step-by-step explanation:
100% SURE
9.5% of 500 = 47.5
9.5% × 500 =
(9.5 ÷ 100) × 500 =
(9.5 × 500) ÷ 100 =
4,750 ÷ 100 =
47.5;
Answer:
A. $2.89(m)=$40
B. 13 songs
Step-by-step explanation:
$2.89(m)=$40
m=$40/$2.89
m=13.84
She can download a maximum of 13 songs
Check:
$2.89 (13 songs)=$37.57
$40-$37.57=$2.43 left on her gift card
m=13.84, check that 0.84 of the cost of a song is left over 0.84*$2.89=$2.43
