Answer:
y = -6
Step-by-step explanation:
On the coordinate plane, the vertical axis (up and down) is the y-axis and the horizontal axis (side to side) is the x-axis. However, when there is a horizontal line on the graph, it represents a value of y that is true for any value of 'x'. In the same respect, a vertical line is a value of x that is true for any value of 'y'. In the case of the point (5, -6), a horizontal line would have to be y = -6 in order to pass through the point and cross the coordinate plane from left to right.
Answer:
Step-by-step explanation:
In order to write the equation of the line in point-slope form that goes through those points, we need to know the slope of that line. Therefore,
So the slope is 2. Now we'll pick a point and use it to write an equation in point-slope form. I'll use the first point given to see if that's the one used in any of the answers : (10, 5)
y - 5 = 2(x - 10). That's choice B. Let's see, just in case there are 2 answers to this, what the equation would be using the other point (4, -7):
y - (-7) = 2(x - 4) and simplified:
y + 7 = 2(x - 4) is the other equation. Since that's not a choice, the only answer is B
