The best interpretation is that the sum of 2.1 and –1.2 times a number is greater than or equal to 8.
<h3>Inequality functions</h3>
Inequality are expressions not separated by an equal sign, Given the inequality;
2.1 + (-1.2x) ≥ 8
The sign ≥ means greater than or equal to
The expression 2.1 + (-1.2x) ≥ 8 can also be expressed as 2.1 - 1.2x ≥ 8
The best interpretation is that the sum of 2.1 and –1.2 times a number is greater than or equal to 8.

Answer:
y-3=4(x-10)
Step-by-step explanation:
Point Slope Form: y-y1=m(x-x1)
Where m=slope and (x1, y1) is a point on the line.
m=(y2-y1)/(x2-x1)=(11-3)/(12-10)=8/2=4
So the slope is 4,
y-3=4(x-10)
