(-8, 3)<br> (-3, -4.5)<br> The graph of the linear function What is the zero of g?
Vlada [557]

9514 1404 393

Answer:

  -6

Step-by-step explanation:

The slope of the line is ...

  m = (y2 -y1)/(x2 -x1)

  m = (-4.5 -3)/(-3 -(-8)) = -7.5/5 = -1.5

Then the point-slope equation can be written as ...

  y -k = m(x -h) . . . . . line with slope m through point (h, k)

  y -3 = -1.5(x +8) . . . equation of the line through the given points.

We want the value of x for y = 0, so ...

  -3 = -1.5(x +8)

  2 = x +8 . . . . . . . divide by -1.5

  -6 = x . . . . . . subtract 8

The x-intercept of this linear function is x = -6.

_____

<em>Additional comment</em>

In slope-intercept form, the function can be written as ...

  g(x) = -1.5x -9

What is the equation of the line shown in the graph? A function graph of a line with two points (-3,-2) and (-1,2) with an x axi
Svetllana [295]
Y=(1/2 x)-2

My Work:
Say that the slop is "a" and that the y-intercept is "b".

For the slope:
First coordinate equation: -3=-2a+b
Second coordinate equation: -1=2a+b
Combine the equations. -3-(-1)=-2a-(2a)+b-(b)
Break down the parenthesis. -3+1=-2a-2a+b-b
Simplify the equation. -2=-4a
Divide both sides by -4 to get the answer to the slope. a=1/2

For the y-intercept:
Use the second coordinate's equation and the now known slope. -3=-2*1/2+b
Multiply -2 by 1/2 (Order of Operations). -3=-1+b
Add +1 to both sides to cancel the -1. -3+1=b
Finally, solve the solve -3+1 to get the answer to the y-intercept. b=-2
