Jeremy wants to buy a desktop
computer that costs $1,600. He has
already saved $1,280. What percent
of the total has he saved?

80%

Step-by-step explanation:

1280/1600=0.8=80%

b. 2

step-by-step explanation:

the slope of a line =δy/δx

δy= y₂-y₁

δx= x₂-x₁

therefore, using the points (-2,-3)   and (3,7) we can calculate gradient as follows:

m=(7--3)/(3--2) (a number minus a negative number the sign changes to a plus)

m=(7+10)/(3+2)

=10/5

=2

it is probably the graph on the bottom right.
