Find the equation for the line graph below in either slope-intercept or point-slope form. (will pick brainiest)

Step-by-step explanation:

The slope-intercept form of an equation of a line:

m - slope

b - y-intercept (0, b)

The formula of a slope:

We have the points:

(0, 4) → y-intercept (b = 4)

(3, 6)

Substitute:

Finally we have the equation:

see explanation

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 ) = (- 3, 2) and (x₂, y₂ ) = (0, 4) ← 2 points on the line

m = =

note the line crosses the y- axis at (0, 4) ⇒ c = 4, hence

y = x + 4 ← in slope- intercept form

OR

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

here m = and (a, b) = (3, 6), hence

y - 6 = (x - 3) ← in point- slope form

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value
