Find the slope of the line first using 
(3, 4), (2, -1)
= 5
Now use y - y1 = m(x - x1) to make an equation in slope-intercept form. Plug the numbers into the formula.
y - (-1) = 5(x - 2)
y + 1 = 5x - 10
y = 5x - 11
The equation of the line in slope-intercept form would be y = 5x - 11.
(3, 4), (2, -1)
Now use y - y1 = m(x - x1) to make an equation in slope-intercept form. Plug the numbers into the formula.
y - (-1) = 5(x - 2)
y + 1 = 5x - 10
y = 5x - 11
The equation of the line in slope-intercept form would be y = 5x - 11.
Answer:
1. 516 ppm; 2. 561 ppm
Step-by-step explanation:
1. CO₂ increase at old rate
Time = 2100 - 2010 = 90 years
Increase in CO₂ = 90 yr × (1.4 ppm/1 yr) = 126 ppm
CO₂ in 2010 = 390 + 126 = 516 ppm
At the old rate, the CO₂ concentration in 2100 will be 516 ppm.
2. CO₂ increase at new rate
Time = 2100 - 2010 = 90 years
Increase in CO₂ = 90 yr × (1.9 ppm/1 yr) = 171 ppm
CO₂ in 2010 = 390 + 171 = 561 ppm
At the new rate, the CO₂ concentration in 2100 will be 561 ppm.
