Question

Write a rule for the linear function shown in the graph.

y = 3x – 1



y =
`(2)/(y5)`x +1



y = -
`(5)/(2)`x -1



y =
`(5)/(3)`x +1

Answer 1

Solve for the first variable in one of the equations, then substitute the result into the other equation.

Point Form:

( 1 , − 2 )

Equation Form:

x = 1 , y = − 2

Explanation:

Graph.

y = 3 x − 1

y = x + 1

y = − x − 1

y = x + 1
