What is the slope intercept form of the equation of the line that passes through the points (9,5) and (4,1)
1 answer:
Answer:
y = 4/5 x - 2 1/5
Step-by-step explanation:
1. Find the slope:
1 - 5/ 4 - 9 = 4/5 = m
2. Find b by plugging in the m and one of the points given into y = mx + b
1 = 4/5 ( 4) + b
1 = 16/5 + b
-2 1/5 = b
3. Write the equation using the m and the b you just found
y = 4/5 x - 2 1/5

Answer:
$14.4
Step-by-step explanation:
20%= .2
$18 x .2 = $3.60
$18 - $3.6 = $14.4
Slope is 4
Y-intercept is 11
5+5= 10
10 time 9b is 90b
10 times -7 is -70
Then 90b-70
