Slope intercept form is simply
where y and x are the things we see on the graph
m is the slope
and b is the y-intercept
the y-intercept is just what y is equal to when x is 0, so right at the middle of the graph.
so just go ahead and if in!
The midpoint between (2,-5) and (4, -7) is Option D.(3-6)
Step-by-step explanation:
Given:
Points (2,-5) and (4, -7)
To Find:
Midpoint of the points=?
Solution:
The midpoint that lies between the two points is given by
Where
= coordinates of the midpoint
= coordinates of the first point
= coordinates of the second point
we have,
Substituting the values in the mid point formula,
(x,y)=(3,-6)
First we take the number as it is. Second, we look at the last number. 6 is rounds up to ten which rounds the 3 up to a 4. So now we come up with 8.4, but that isn't a whole number. We can then round 4 to 0 because it's closer to 0 on a number line. Now, our answer is 8.0, but, in order to have a whole number, we can't have any decimals. we can, then, take away the 0 and the decimal, which leaves us 8, and 8 is a whole number; we can now say the answer is 8. :)
Answer:
The dimensions on the scale drawing would be 1 inch by 0.8 inches.
The scale is 1 in: 10 ft; since the actual width of the deck is 10 ft, then it will be 1 inch on the scale. To find the width:
1/10 = x/8
Cross multiply:
1*8 = 10*x
8 = 10x
Divide both sides by 10:
8/10 = 10x/10
0.8 = x
The width on the scale drawing will be 0.8 inches.
