There is a line whose y-intercept is 9 and whose slope is 0. The point (1, –9) What is its equation in slope Y-intercept form?

Question

What is the equation of y=?

Answer 1

slope = 0 = m

y intercept = 9 = b

y = mx +b in slope intercept form, plug in m=0 and b=9 to get

y = (0)x + 9

or simply

y = 9

Answer 2

Slope -intercept form is y = mx + b, where m is the slope and b is the y-intercept. So, if the slope was 2 and the y-intercept was 4, the equation would be y = 2x + 4. Given that information, you should be able to write the equation with the slope and y-intercept you were given.
