slope intercept

Question

slope 0.25, passes though (0,4)

Answer 1

slope=m, and y-intercept=b

m=0.25 or 1/4 in fraction form

(x,y)= (0,4) implies that when x=0, y=4 which means (0,4) is also your y-intercept

so b=4

rewrite y=mx+b by replacing m=0.25 or 1/4 and b=4

now you have the slope intercept form

y=0.25x+4 or y=1/4 x+4

Answer 2

m=0.25 = 1/4

y-y₀ = m(x-x₀)

y = (x-0)/4+4

y=x/4+4 = 0.25x+4
