The slope = 4
y-intercept = -3
The equation of a line in slope intercept form is written as y=mx+b
where m is the slope and b is the y-intercept.
replace m and b with the given information:
The equation is: y = 4x-3
Answer: 4n^2
Step-by-step explanation: -3n^2 - (-7n^2) = -3n^2 + 7n^2= 4n^2. When adding and subtracting the exponents stay the same only the coefficients are subtracted or added
Let's suppose Sarah's age is s and Paul's age is p.To find Paul's age it would be P=5s-8 because it says that Paul's age is 8 less, or 8-, 5 times Sarah's age, so 5s. that would make the equation p=5s-8.
