Answer:
y= -2x-7
Step-by-step explanation:
Start with the linear equation formula.
y= mx+b
identify what you already have.
x= -2 and y= -3 m(slope)= -2
we are trying to find b, so plug in what you have.
-3=-2(-2)+b
simplify.
-3= 4+b
subtract 4 on both sides.
-7= b
set up your equation without the x and y value.
y= -2x-7
Answer:
17/25
Step-by-step explanation:
In this case we are asked for the probability that a random point is chosen in the lower grid in the shaded area, we must count the total number and amount of shaded squares.
In total there are 25 squares and 17 shaded ones.
This means that the answer is 17/25, the answer is not within the options, but if it is 8/25, which would be the probability of choosing a random point in a non-shaded or white area
