What is the slope that passes through the lines (2.1,-4.2) and (2.5,-5)
1 answer:
slope = (y2-y1)/(x2-x1)
= (-5--4.2) /(2.5 -2.1)
(-5+4.2)/(2.5-2.1)
=-.8/.4
m=-2
the slope is -2

Answer:
8x + 12y = 4800
Step-by-step explanation:
They have the exact same value so you just divide by 1
0.85x-100<80
collect like terms
0.85x<80+100
0.85x<180
divide by 0.85
x<211.8
