If l is the line having x -intercept of -1 and y -intercept of 3, complete the equation of l .
y = -x + 3
y = -3x + 3
y = 3x + 3

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 = = 3

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

y = 3x + 3 ← equation of line

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1
