Answer:
5/2, 5/2, -3= (5/2)(2)+b, -8, y=(5/2)x-8
Step-by-step explanation:
Answer:
f(-2)=4(-2)+1= 7
Step-by-step explanation:
100-30=70-50=20
there's your equation
Becouse k and n are 'neighbours' so their sum are 180
so k=180-42=138
Slope-intercpet is y=mx+b where m=slope
b=y intercept
convert
-2x+7y=28
add 2x to both sides
7y=2x+28
divide both sides by 7
y=2/7x+4
slope=2/7
y-intercept=4 or the point (0,4)
