Answer: y = 3x - 19
Step-by-step explanation:
The equation of line in the slope intercept form is give as :
y = mx + c , where m is the slope and c is the y - intercept.
The points given : ( 4 , -7 )
slope = 3
Using the formula
y - = m (x -
)
substituting the given values , we have
y - (-7) = 3 ( x - 4 )
y +7 = 3x - 12
y = 3x -12 - 7
y = 3x - 19
This gives the equation of the line in slope - intercept form.
Answer:
25 pounds
Step-by-step explanation:
Let us assume that initially, 1 pound of whole chicken costs x.
So, initially 20 pounds of whole chicken costs 20x.
Now, the price is reduced by 20%.
That means that 1 pound of whole chicken now costs
Therefore, with a 0.8x amount of money, we can now purchase 1 pound of the whole chicken.
Hence, with a 20x amount of money, we can now purchase pounds of the whole chicken.
