X=adults and c=children
x+c=127
9x+6c=1,053
Multiply the first equation by negative 6.
-6x+(-6)c= -762
Add the equations together.
3x=291
x=97
97+c=127
c=30
There were 30 children and 97 adults.

What is the equation in point-slope form of the line that passes through the point (3, −2) and has a slope of 23 ?
Oksanka [162]
Use the point slope formula. then, substitute the values inside the formula.

x1 =3
y1= -2
m = 23

y -y1 = m ( x - x1)

y - (-2) = 23 (x - 3)

y + 2 = 23 ( x - 3)
