Lina and Michael studied the data in the table. They each wrote an equation to represent the relationship between the number of miles and the numbers of hours ridden by each bicyclist. Data : Miles, m ; Hours, h | 27m = 3h ; 45m = 5h ; 18m = 2h and 54m = 6h

Lina's equation: m = 9/h

Michael's Equation: h = 1/9m

The teacher said both of their answers were correct.. why?

step-by-step explanation:

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form
