Answer:
y=3/2 x + 5
Step-by-step explanation:
<em>Firstly, find m (gradient).</em>
m= (y1-y2)/(x1- x2)
m= 8-(-1)/ 2-(-4)
m= 9/ 6
m= 3/2
<em>Please leave gradient in improper fraction if its value is not a whole number.</em>
<em>Now substitute m into the equation:</em>
y= 3/2 x + c
<em>Then substitute a coordinate to find c:</em>
When y= 8, x= 2,
8= 3/2 (2) + c
8= 3 + c
c= 8 - 3 = 5
Thus, the equation of the line is y= 3/2 x + 5.
Answer:
New price of the ball after discount = $16.65
Step-by-step explanation:
Selling price of the soccer ball = $45
Discount labeled on the ball = 63% off
Therefore, selling price after the discount = Original selling price - %discount
= $45 - (63% of $45)
= $45 - $28.35
= $16.65
New price of the ball after discount = $16.65
