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

Select all of the relations that are functions. {(a, 1), (b, 1), (c, 1)} {(a, a), (a, b), (a, c)} {(1, a), (2, a), (3, a)} {(a,
netineya [11]

Answer:

{(a, 1), (b, 1), (c, 1)}, {(1, a), (2, a), (3, a)}, and {(a, a), (b, b), (c, c)}

**All functions are relations, but not ll relations are functions**

In a function, the x values CAN NOT repeat, only y-values can.
