Determine 2 coordinates
I used (-8,4) and (0,-2)
To determine the slope, use delta y divided by delta x.
m = (4 - (-2))/(-8 - 0)
m = 6/-8
m = -3/4
Therefore the slope is -3/4.
Answer:
Step-by-step explanation:
It means how many roots are there.
For example: The first one has no solution. But the second one has two solutions, 3 and 1.
Which means two x-values.
Hope this helps!

Answer:
Bill spent $988 on taxes.
Step-by-step explanation:
First, you have to find the total amount that Bill spent last month on taxes and groceries as the statement says that he spent 40% of the total amount on that:
$6,000*0.4=$2,400
Then, the statement indicates that the total amount Bill spent on taxes was 70% of the amount he spent on groceries.
Let's consider that:
x=taxes
y=groceries
With the information we can write the following:
x+y=2,400 (1)
x=0.7y (2)
You can replace 2 in 1:
0.7y+y=2,400
1.7y=2,400
y=2,400/1.7
y=1,412
Then, you can replace the value of y in 2:
x=0.7(1,412)
x=$988
According to this, Bill spent $988 on taxes.
