Answer:
m = - 
, c = - 
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 )
Given
2x + 3y + 1 = 0 ( subtract 2x + 1 from both sides )
3y = - 2x - 1 ( divide terms by 3 )
y = - x - ← in slope- intercept form
with m = - and c = -
The continent which has 59% of the total population will have more than 5.31 billion people by 2050.
<u>Step-by-step explanation:</u>
It is given that,
- The total number of people is 9 billion.
- The estimated number of people in 2050 year is 5.31 billion.
Therefore, you need to find out which continent has the estimated number by finding the percentage value.
<u>To find what percent 5.31 is of billion is of 9 billion :</u>
Let x be the percentage to be calculated.
⇒ x percent of 9 billion is 5.31 billion.
⇒ (x/100) × 9 = 5.31
⇒ x = (5.31 × 100) / 9
⇒ x = 531 / 9
⇒ x = 59 %
∴ The continent which has 59% of the total population will have more than 5.31 billion people by 2050.
The equation of the line has the form: y = ax+b parallel to the line y = -2x + 7
=> a= -2
Passes through (4,1) => x=4, y=1
Substituting into the equation:
1= -2x(4) + b => b= 9
=> y= -2x + 9
