Answer:
y- intercept = - 2.5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (1, - 7) and (x₂, y₂ ) = (5, - 25)
m = 
= 
= - 4.5 , then
y = - 4.5x + c
To find c substitute either of the 2 points into the equation
Using (1, - 7), then
- 7 = - 4.5 + c ⇒ c = - 7 + 4.5 = - 2.5
y- intercept c = - 2.5
Answer:
SP = 1274
Discount 9%
Selling price = MP (100 - d) / 100
1274 = MP (100 - 9) / 100
1) MP = 1400
i) After 5% discount = 1400 x 0.95 = 1330
After 4% discount = 1330 x 0.96 = 1276.80
