7-68. SITUATION GRAPH
A virus has invaded Leticia's favorite mountain fishing lake. Currently there are an estimated 1800 trout in the
lake, and the Fish and Game Department has determined that the rate of fish deaths will be one third of the
population per week if left untreated.
a) Sketch a graph showing how many
b) Theoretically, will the trout ever disappear from
fish are left in Leticia's favorite lake
the lake? Use the graph to justify your answer.
over several weeks.

one way is to plot 2 points and connect them which is what the answer choices seem to be doing

it seems to be using the y intercept and the slope

y=mx+b, m=slope, b=y-intercept (where the line hits the y axis)

slope=rise/run

y-intercept is where the line croses the y axis which is the y value where x=0

you seem to have given the wrong slope (you didn't put a number in front of te x, it should be 2/3 or 3/2 looking at the answer options)

y=? x-1

m=? because of your fault

b=-1

so it has a slope of ? and y intercept of -1, meaning it pases through (0,-1)

so draw point (0,-1) (so answer is one of the first 2 option)

if slope is 2/3, then go up 2 and right 3 then draw line through those 2 points

if slope is 3/2, then go up 3 and right 2 then draw line through those 2 points

pi or 3.14159265359 is an irratinal decimal

it would be c. 25 units

x=3y-6

step-by-step explanation:

solve for   x by simplifying both sides of the equation, then isolating the variable.
