Graph the equation y = k x + 1 if it is known that the point M belongs to it:
M (2, −7)

y = k x + 1

(1,3)

3 = k(1) + 1

2 = 1k

k = 2

Step-by-step explanation:

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950

step-by-step explanation:

this is not a question
