19. A teacher tells 36 students to form 4 equal groups. Write and solve a
olchik [2.2K]

4 x = 36

Step-by-step explanation:

Because the groups have an equal number of students, we assume that each of the groups has <em>x </em>number of students.

Therefore since there is <em>x</em> number of students in each of the 4 groups, there is 4 * x number of total students in all groups combined.

Since the question already indicates that there are a total of 36 students in the class, then we can indicate that..

4x = 36

Which equation is a point slope form equation for line AB?
sukhopar [10]

Answer:

option 1

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Calculate m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = A(1, 6) and (x₂, y₂ ) = B(5, - 2)

m = \frac{-2-6}{5-1} = \frac{-8}{4} = - 2

Use either of the 2 points for (a, b)

Using (a, b) = (5, - 2) , then

y - (- 2) = - 2(x - 5) , that is

y + 2 = - 2(x - 5)
