Lindsay is 5 years younger than Mark. Seven years ago, the sum of their ages was
31.
let l be Lindsay's age and let m be Mark's age. Which system of equations represents this situation?


l−7=(m−7)+5
l+m=31




l=m+5

(l−7)+(m−7)=31




l−7=(m−7)−5

l+m=31


l=m−5

(l−7)+(m−7)=31

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
