Need help defining these functions. HELP PLEASE :):)?

Question

(a) A line with a slope of 3, passing through the point (5,5)
(b) A horizontal line with a y-intercept of 8.
(c) A line that passes through the points (11,8) and (12,3)
(d) A horizontal line y=3


How would you define these functions? Thanks soooo much for the help! :)

Answer 1

Remember y = mx + c

where m is the slope.

But what do you mean define ?

(a) y = 3x - 10

(b) y = 8

(c) slope = -5
y = -5x + 63

(d) er
