If L is the line having x -intercept of -1 and y -intercept of 3, complete the equation of L .
frozen [14]

Answer:

y = 3x + 3

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 = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 1, 0) and (x₂, y₂ ) = (0, 3)

m = \frac{3-0}{0+1} = 3

We are given the y- intercept, that is c = 3

y = 3x + 3 ← equation of line
