Write an equation for the graph, where y depends on x.

y = -3x + 6

Step-by-step explanation:

Equation of straight line is given by,

y = mx + b

m = slope of the line

b = y-intercept

From the graph attached,

m =

   =

   = -3

y intercept 'b' = 6

Therefore, equation of the line will be,

y = -3x + 6

see attached

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
