Answer:
Slope = -4
Step-by-step explanation:
Given points are :
(-1,30) and (4, 10)
We need to find the slope of the line that passes through these points.
We know that, the formula for the slope of line is given by :

We have, x₁ = -1, y₁ = 30, x₂ = 4 and y₂ = 10
Put values in the above formula.

So, the slope of the line is -4.
Answer:
y=-2x+7
Step-by-step explanation:
Hi there!
The form of slope-intercept form is given as y=mx+b, where m is the slope and b is the y intercept
We are given the slope (-2) and a point (3,1)
We can immediately substitute -2 as the slope in the equation
y=-2x+b
Now we need to find b
Because the line will pass through the point (3,1), we can use it to solve for b
Substitute 3 as x and 1 as y
1=-2(3)+b
multiply
1=-6+b
add 6 to both sides to isolate b
7=b
Substitute 7 as b into the equation
The line is <u>y=-2x+7</u>
Hope this helps!
Answer: 68 minutes or 1 hour and 8 minutes spent in all putting up the fence
Step-by-step explanation:
(4/5) x 60 = 48 minutes
4/5 is the same as 0.8, which is what you get when you divide four by 5
So, 0.8 x 60 = 48 is also acceptable
Then,
(1/3) x 60 = 20 minutes
1/3 is the same as 0.333333333333, which is what you get when you divided 1 by 3
So, 0.33333(and so on) x 60 = 20
- Typically, you can round 0.3333333 down to something like 0.333 which should give you a similar answer
Then, as it asks you for how much time he spent in all, you add those two together
48 minutes + 20 minutes = 68 minutes OR 1 hour and 8 minutes (There is sixty minutes in 1 hour, so subtract the 60 from 68 and then you have 8 minutes left, thus 1 hour and 60 minutes)
