m = y1 - y2 / x1 x2
-3 = -2 - 7 / 6 - a
-3 = -9 / 6 - a
-3 (6 - a)=-9
-18 + 3a = -9
3a = - 9 + 18
a = 9 / 3
a = 3
Answer:
Step-by-step explanation:
The slope of a line given two points can be found by using the formula
From the question the slope is - 3
To find the value of a we have
Divide both sides by - 3
We have the final answer as
Hope this helps you
x^2 - 2x = 146
x^2 - 2x - 146 = 0
See attachment. The quadratic formula is needed in this case.
There is one 12/4 in 3.
12/4 = 3
4/4 + 4/4 + 4/4 = 12/4 = 3
x=96
