Answer:
Step-by-step explanation:
You would first need to find the slope. The Slope formula is m = (y2 - y1)/(x2 - x1). In your problem, (1, 2) could be (x1, y1) and (2, 5) could be (x2, y2). Substitute those values into the Slope formula to find m which is your slope.
The point-slope form of a line is y - y1 = m(x - x1). You already have (x1, y1) to substitute in so do that and also substitute in your m.
Answer:
Hey there!
Angle C is opposite to side AB, because it is opening towards that line segment.
Let me know if this helps :)
Answer:
Not a solution
Step-by-step explanation:
In order for 
to be a solution, the result after substituting must be 0:
Therefore, is not a solution to 
7c+ 12= -4c+ 78
⇒ 7c+ 4c= 78 -12 (inverse operation)
⇒ 11c= 66
⇒ c= 66/11 (inverse operation)
⇒ c= 6
Final answer: c= 6.
Answer:
Slope, m = 1/4 = 0.25
Step-by-step explanation:
Slope,m of a line on a graph is derived from the formula,
Slope, m = change in value of y ( on the vertical axis) divided by change in the value of x ( on the horizontal axis)
change in value of y = final value of y (y2) - initial value of y (y1)
change in value of x = final value of x (x2) - initial value of x (x1)
From the graph, we will pick corresponding points.
Final value of y, y2 = 6
Initial value of y, y2 = 5
Final value of x, x2 = 0
Initial value of x, x2 = -4
Slope = (y2-y1) / (x2-x1)
= (6 - 5)/0 - - 4 = 1 / 4
= 0.25
