B) The diagram shows a straight line L.

i) Find the equation of line L.​

y = - 2x + 6

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 =

with (x₁, y₁ ) = (0, 6) and (x₂, y₂ ) = (3, 0) ← 2 points on the line

m = = = - 2

The line crosses the y- axis at (0, 6 ) ⇒ c = 6

y = - 2x + 6 ← equation of line

what i would say the best answer is a. 40.5

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
