Answer:

Slope = 2/3

y-intercept = (0,-4)

Equation:

y = 2/3x - 4

Step-by-step explanation:

Slope formula:

y₂ - y₁ / x₂ - x₁

Take two points from the line:

(6,0) and (3,-2)

-2 - 0 / 3 - 6

-2 / -3

2/3

The line crosses the y axis through point (0,-4)

Answer:

y=mx+c(what i learn't, but it doesn't make a difference) or y=mx+b

gradient = rise/run = (upward slope) [tex]\frac{2}{3}[/tex]

so y= [tex]\frac{2}{3}[/tex] x+c

to find c, input values for x and y, take any point from the graph.

(3,-2)

-2=(2/3)*3+c

-2=2+C

-4=c

so y=(2/3)x+(-4)
