Ayoung sumo wrestler decided to go on a special high-protein diet to gain weight rapidly. when he started his diet, he weighed 79.579.579, point, 5 kilograms. he gained weight at a rate of 5.55.55, point, 5 kilograms per month.
let yyy represent the sumo wrestler's weight (in kilograms) after xxx months.
which of the following could be the graph of the relationship?

Step-by-step explanation:

Let y represent the sumo wrestler's weight (in kilograms) after x months.

When he started his diet, he weighed 79.5 kilograms, this means x = 0 months, y = 79.5 kg. So, y-intercept is at point (0, 79.5).

He gained weight at a rate of 5.5 kilograms per month, so the slope of the linear function is 5.5.

Hence the equation of the linear function in the slope-intercept form is

The graph of this function is attached.

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
