Answer:
see explanation
Step-by-step explanation:
(1)
Calculate the slope m using the slope formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (0, 3) and (x₂, y₂ ) = (4, 0) ← 2 points on the line
m = [tex]\frac{0-3}{4-0}[/tex] = - [tex]\frac{3}{4}[/tex]
(2)
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
note the line crosses the y- axis at (0, 3) ⇒ c = 3
y = - [tex]\frac{3}{4}[/tex] x + 3 ← equation of line
