Answer:
y = 6
Explanation:
All horizontal lines have a slope of 0. Also, all horizontal lines have an equation in the form:
y = anumber
In your problem, the line has slope, 0. So its horizontal and the equation y = anumber, well, what is that number? Let's look at the point given: (10,6) this point is in the form (x,y)...so y is 6. That's the equation!
y = 6
Also, slope-intercept form of the equation is
y = mx + b
m is slope, so fill in 0. And because we know the point (10,6) is (x,y) we can fill in 10 for x and 6 for y.
6 = 0•10 + b
6 = b
Fill in 0 for m and 6 for b.
y = 0x + 6
y = 6
Same answer. I like the first way better. But the second way works for all kinds of lines.
