Answer:

y=-4x+2

Step-by-step explanation:

Hi there!

We want to find out which equation represents a line with a slope of -4 and a y intercept of (0,2)

The most common way to write the equation of the line is in slope-intercept form, which is y=mx+b, where m is the slope and b is the y intercept

We have everything we need to plug into the equation, let's just label the values to avoid confusion

m=-4

b=2 (when you substitute the y intercept as b, b is the value of y in the point)

Now substitute into the equation

y=-4x+2

Hope this helps!

What is the slope between (14,-8) and (7,-6)

djyliett [7]

Answer:

$- \frac{2}{7}$

Step-by-step explanation:

Slope formula:

$\boxed{ slope = \frac{y _{1} - y_2 }{x_1 - x_2} }$

where (x₁, y₁) is the first coordinate and (x₂, y₂) is the second coordinate

Slope

$= \frac{ - 8 - ( - 6)}{14 - 7}$

$= \frac{ - 8 + 6}{7}$

$= - \frac{2}{7}$

What is the minimum number of fish in the pond? (Hint: You caught 100 fish both days, but you caught 3 of the same fish twice.)

nevsk [136]

Answer:

197

Step-by-step explanation:

So, if you catch 100 fish on both days, that means that you have caught 200 fish. 100 on one day and 100 on the next. But, since you've caught 3 fish twice, that means that three out of 200 fish are the same and cannot be counted as new fish. So 3 from 200 is 197 fish. Hope this helped!

Day 1: 100 (3 tagged)

Day 2: 97 (3 tagged)

100+97=197

Day 1: 100 (3 tagged)

Day 2: 100 (3 tagged)

100+100= 200

200-3=197

Answer, 197 fish.
