Well when you are using a fraction strip, it tells you fractions that are equivalent. To know how to fractions are equivalent, then you have to work it out writing out different sets of fractions and seeing if they are the same.
Answer:
y = 5x - 1
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 )
Calculate m using the slope formula
m =
with (x₁, y₁ ) = (1, 4) and (x₂, y₂ ) = (2, 9)
m = = = 5 , then
y = 5x + c ← is the partial equation
To find c use any ordered pair from the table and substitute into the partial equation.
Using (3, 14 ) , then
14 = 15 + c ⇒ c = 14 - 15 = - 1
y = 5x - 1 ← equation of line
