slope intercept form

Question

Write a linear function in slope-intercept form or point-slope form with the values f(2) = 4 and f(-1)=4.

Answer 1

(2,4), (-1,4) have a line through them: y=4

slope = m = 0, y intercept = b = 4

y=mx+b

y = (0)x +4 in slope intercept form

y-4 = (0)(x-2) in point slope form

or

y-4 = (0)(x- -1) in point slope form

but either form simplifies to just

y=4,

a flat horizontal line with slope = 0
