The rule for reflecting over the X axis is to negate the value of the y-coordinate of each point, but leave the x-value the same. For example, when point P with coordinates (5,4) is reflecting across the X axis and mapped onto point P', the coordinates of P' are (5,-4).
I need the picture to answer it
Step-by-step explanation:
because
√(11)²+9²=√202=14,2
I hope that helps, coz l've done what i know
For the X intercept you set y = 0 and solve for x
Y =

x + 9
0=

x + 9 subtract 9 from both sides
-9 =

divide both sides by 3
-3 = -8x divide both sides by -8

= x
X-intercept = (

, 0)
