I'm really confused on point-slope form, and slope-intercept form. Can anyone help?

Point slope form is

Y-y1=m(x-x1)

-in this^ u only should put number in the y1, m, and x1
-m is your slope

Slope intercept form is

Y=mx+b

-start out with putting numbers in m and b and then you'll find your way to your y and x

A blueprint for a house states that 2.5 inches equal 10 feet. If the length of a wall is 12 feet how many inches is the wall in
Xelga [282]
If 10 feet = 2.5 inches
then 1 feet = 2.5/10 = 0.25
therefore 12 feet = 3 inches

In short the answer is 3 inches on the blueprint

The spinner shown is divided into congruent sections that are labeled from 1 through 7. If the spinner is spun one time, what is
adoni [48]

Answer:

3/7

Step-by-step explanation:

The number of possible results are;

1, 2 , 3 , 4 , 5, 6 , 7 = 7

odd numbers here are;

1, 3 , 5 and 7

non-odd numbers are 2, 4 and 6

So the section not labeled with an odd number is 3

Hence the probability here is that;

3/7

Write the equation of the line for a line that passes through (-2,-4) and (-1, -1).
Bas_tet [7]

Answer:

y = 3x+2

Step-by-step explanation:

First find the slope using the slope formula

m= (y2-y1)/(x2-x1)

   = ( -1 - -4)/(-1 - -2)

   = (-1 +4)/ (-1 +2)

   = 3/1

  = 3

The slope intercept formula is

y = mx+b where m is the slope and b is the y intercept

y = 3x+b

Using the point (-1,-1) and substituting into the equation

-1 = 3(-1)+b

-1 = -3+b

-1+3 = b

2 = b

y = 3x+2
