A line that has a rise of -34 and a run of 20.
aleksandr82 [10.1K]

Answer:

y=-1.7x-34

Step-by-step explanation:

An equation of a line is given y=mx+c, where m is the gradient or \frac{Rise}{Run}

The rise indicates the change in value of y (vertical change in the graph).

The run indicates the change in value of x (horizontal change in the graph).

Let point 1 of the graph be (x,y) = (0,-34) and point 2 be (x,y) = (20,0).

 m =\frac{Rise}{Run} \\  =\frac{-34}{20}\\  =-1.7

Substitute point 1 into the graph to get the constant c.

y=mx+c

-34=(-1.7)*(0)+c

c=-34

∴ The equation of the line is, y=-1.7x-34

Grade 8 math question plz show work

A. The population would be 120

You would find 20 percent of 100
To do that, you do 100× 0.2 and add that to 100

B. The population doubles

10×2= 20
20×2= 40, not 30

hope this helps!
