Question

Write the equation for the horizontal line passing through (4, -6).

Answer 1

So, first off you should know what the slope-intercept formula is. Then, you should know what slope a horizontal line has, and afterwards, you solve to see the y-intercept.

Answer 2

So, do you know the slope-intercept formula?

Answer 3

no

Answer 4

Okay then. The slope-intercept formula is...\[y=mx+b\]This is where y is the y-value, m is the slope, x is the x-value, and b is the y-intercept.

Answer 5

y=mx+b

Answer 6

So, a horizontal line ALWAYS has a slope of zero. That's why it's a 0-slope. That gives you what to input for "m". So, if you have a line that has zero slope, it's just a horizontal line, which number do you think is the y-intercept?

HINT: A horizontal line always has the same y-value.
