Answer:

Step-by-step explanation:
Coordinates are (0,6) and (1,3)
Slope = 
Slope = 
Slope = -3
<u><em>Now, Finding b</em></u>
Taking any Point
Point = (x,y) = (0,6)
So, x = 0, y = 6
<em>Putting in slope-intercept form to find b</em>

=> 6 = (-3)(0)+b
=> b = 6
<u><em>Now Putting slope and b in the formula to get the required slope-intercept form.</em></u>

=> 
Answer:
Step-by-step explanation:
total price was reduced by $ 7
let x = the total price........ x - 7
he bought 10.....and it cost him $ 130
10(x - 7) = 130
10x - 70 = 130
10x = 130 + 70
10x = 200
x = 200/10
x = 20 <====== original price
