Ireally don’t get this and i just want to understand it.. someone .. will mark brainliest

f(x) = 2/3x-2

Step-by-step explanation:

We know the y intercept (where it crosses the y axis) is -2

We can find the slope from two points

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

m = (y2-y1)/(x2-x1)

   = (0--2)/(3-0)

   = (0+2)/(3-0)

   = 2/3

The slope is 2/3

The equation can be written in the form

y= mx+b where m is the slope and b is the y intercept

y = 2/3x-2

Replace y with f(x) for it to be in function notation

f(x) = 2/3x-2

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
