Which ordered pair is the reflection of (3, 10) across the x-axis? a.(3,-10) b.(10,3) ,10) ,-10)

Option A is correct.

The ordered pair is the reflection of (3, 10) across the x-axis is

Step-by-step explanation:

The rule of reflection across the x-axis is given by:

As per the statement:

reflection of (3, 10) across the x-axis

Apply the rule;

therefore, the ordered pair is the reflection of (3, 10) across the x-axis is

y = 3x+4

step-by-step explanation:

to find the slope

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

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
