Write a linear equation from the ordered pair (-2,8)

1 answer:

4 0

The equation of a line that goes through the point (x1,y1) and has a slope of m is
y-y1=m(x-x1)

so, given the point (-2,8)
x1=-2
y1=8

y-8=m(x-(-2))
y-8=m(x+2)
the equation is y-8=m(x+2) where m is the slope
or you could rewrite it to get y=mx+2m+8

Mary is thinking of three consecutive even integers, x, y, and z. Three times the value of z exceeds half the value of x by 37.

Naya [18.7K]

Answer:

x = 10

Step-by-step explanation:

You know z = x+4, so ...

3z -x/2 = 37 . . . . . . . . the given relation

3(x +4) -x/2 = 37 . . . . substituting for z

5/2x +12 = 37 . . . . . . .eliminate parentheses and simplify

5/2x = 25 . . . . . . . . . . subtract 12

x = 10 . . . . . . . . . . . . . multiply by 2/5

_____

<em>Check</em>

3z = 3·14 = 42

x/2 = 10/2 = 5

42 exceeds 5 by 37 . . . . true
