Well,
Slope-intercept form is given as follows:
y = mx + b
In this equation, "m" is the slope, and "b" is the y-intercept.
y = 12x + 7
We can clearly see that the 12 in the equation is the "m" in the general slope-intercept form.
Therefore, the slope of the equation is 12.
Answer:
<em>The length of AB is 40</em>
Step-by-step explanation:
<u>The Midpoint of a Segment</u>
If A and B are the endpoints of a segment, and C is the midpoint of AB, then the distance from A to C is equal to the distance from B to C.
We are given the lengths BC=3x-7 and AC=9x-61:
9x - 61 = 3x - 7
Subtracting 3x:
6x - 61 = - 7
Adding 61:
6x = 54
Dividing by 6:
x = 9
The total length AB is
BC+AC=3x - 7 + 9x - 61 = 12x - 68
Substituting x=9:
AB = 12*9 - 68 = 40
The length of AB is 40
