Answer:
<h2>b = -9</h2>
Step-by-step explanation:
The slope-intercept form of an equation of a line:

m - slope
b - y-intercept
The formula of a slope:

We have the points M(4, 3) and N(7, 12). Substitute:

Therefore we have the equation:

Put the coordinates of the point M to the equation:

<em>subtract 12 from both sides</em>

Each question has four choices, then the probability to guess a correct answer is

Answer:
x=5/12
Step-by-step explanation:
Simplify left side by adding 11x+x
12x+5=10
Get x alone on left side by subtracting 5 on both sides
12x=5
Get X alone by dividing both sides by 12
x=5/12
