Answer:

[tex]\large\boxed{y=\dfrac{2}{3}x+4}[/tex]

Step-by-step explanation:

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

[tex]y=mx+b[/tex]

m - slope

b - y-intercept (0, b)

The formula of a slope:

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

We have the points:

(0, 4) → y-intercept (b = 4)

(3, 6)

Substitute:

[tex]m=\dfrac{6-4}{3-0}=\dfrac{2}{3}[/tex]

Finally we have the equation:

[tex]y=\dfrac{2}{3}x+4[/tex]

Answer:

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 = [tex]\frac{4-2}{0+3}[/tex] = [tex]\frac{2}{3}[/tex]

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

y = [tex]\frac{2}{3}[/tex] 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 = [tex]\frac{2}{3}[/tex] and (a, b) = (3, 6), hence

y - 6 = [tex]\frac{2}{3}[/tex](x - 3) ← in point- slope form
