Wow, what a coincidence, I just learned this at school today!
1. Slope
M= yb-ya/xb-xa
M= 8-4/8-6
M= 4/2
M= 2

2. Y-intercept
Y= mx + b
4 = (2)(6) + b
4 = 12 + b
4 = 12 + b
-12 = - 12 + b
-8 = b

Therefore, the equation is Y = 2x - 8

Solve for −4.2y+2.1>−2.52
Alchen [17]

Answer:

y < 1.1

Step-by-step explanation:

<u>Step 1:  Subtract 2.1 from both sides </u>

-4.2y + 2.1 - 2.1 > -2.52 - 2.1

<em>-4.2y > -4.62</em>

<em />

<u>Step 2:  Divide both sides by -4.2</u>

-4.2y / -4.2 > -4.62 / -4.2

<u><em>Since you divided by a negative, that flips the sign.</em></u>

<em>y < 1.1 </em>

Answer:  y < 1.1
