Answer:
Step-by-step explanation:
Point-slope form is represented by 
. To write an equation with it, we need the slope of the line and a point the line crosses through. We already have at least one point the line crosses through, so let's figure out the slope.
To find the slope, use the slope formula 
. 
and 
represent the x and y values of one point the line crosses, and 
and 
represent the x and y values of another point the line crosses. So, using the x and y values of (1, -6) and (8, 9), substitute them into the formula and solve:
Thus, the slope is 
.
2) Now, using the point-slope form of , substitute 
, , and for real values in order to write an equation in point-slope form. The represents the slope, so substitute in its place. The and represent the x and y values of one point on the line. So, choose any one of the points given - either one is fine - and substitute its x and y values for and . (I chose (8,9)). This gives the following equation and answer:

Step-by-step explanation:
Answer:
m∡ZA = 51°
m∡ZB = 39°
Step-by-step explanation:
∡ZB = 'b'
∡ZA = '12 + b'
b + 12 + b = 90
2b + 12 = 90
2b = 78
b = 39
12 + 39 = 51
c, 10 G this is the answer i have to talk cause it made me have to.
