Answer:
(3;0)
(0;15)
y=-5x+15
Step-by-step explanation:
x-intercept
-5x–0=-15
-5x=-15
-5x/-5=-15/-5
x=3 》》(3;0)
y-intercept
-5(0)-y=-15
y=15 》》 (0;15)
slope intercept form
y=mx+b
m=Y2–Y1/X2–X1
=15–0/0–3
=15/-3
=-5
evalute (0;15) & m=-5 in y=mx+b
15=-5(0)+b
15=b
so
y=-5x+15
Answer:
4/5 times a number Plus 8 answer=b
cuz if you because it says 4 / 5 which would be X so you have to do for as 5 as fraction and then you have to multiply it
