Answer:
m∠ABD = 126°
Step-by-step explanation:
if both angles make a linear pair then their sum equals to 180°
you can solve for x
m∠ABD + m∠CBD = 180
6x-12 + x+31= 180
7x + 19 = 180
7x = 161
x=23; now solve for
m∠ABD = 6x - 12 = 6(23) - 12 = 126°
y=-2x+1
So, -2x, you go down 2 every time you go across 1. So, the rise is -2, and the run is 1, so it's -2x
+1: when you reach an x of 0, you are still up 1. So, the y-intercept is 1

that's the equation for the law
Answer:
15
Step-by-step explanation:
The gradient function is
y1-y2/x1-x2
So the gradient of this line is
2-0/0-(-5)= 2/5
Recall that the linear line function is
y=mx +c ,
m is the gradient while c is the y-intercept
So, the equation of this line is
y= 2/5x + 2
