A line passes through the points (7, 10) and (3, 2). What is its equation in slope- intercept form?
lapo4ka [179]
In order to get an equation is slope intercept form, we need to find the slope.

The formula is:
y2 - y1
———-
x2 - x1

In this case:
10 - 2
———
7 - 3
=
8/4
2

Now that we know the slope, we can plug it into y = mx + b with x and y being x1 and y1.

y = 2x + b
10 = 2(7) + b
10 = 14 + b
-4 = b

Now, we can construct our equation.

y = 2x - 4

Hope this helped!

You should use paper to help this but you gotta make 1 1/4 into an improper fraction start at 3/4 then whatever you get as a improper fraction move it towards that space for example if you get 5/4 you move 5 spaces to your right since your working with positive not negative! I hope this helps you out

State if the three side lengths 3 mi, 12 mi, 13 mi?
marusya05 [52]

Since the sum of any two sides is greater than the third, hence the three sides for the sides of a triangle

<h3>What is a triangle?</h3>

A triangle is a 2-D shape with 3sides and angles. According to the question, we are to determine whether the given measures form sides of a triangle.

For the following measure to form the sides of a triangle, the sum of any two sides must be equal to the third as shown:

3 + 12  = 15 > 13

3 + 13 = 16 > 12

13 + 12 = 25 > 3

Since the sum of any two sides is greater than the third, hence the three sides for the sides of a triangle
