7. for the equation y = -1/4x 8 state
the slope and the y-intercept.

slope = -1/4

y-intercept = 8

Step-by-step explanation:

In the equation y = -1/4 x + 8

The slope is -1/4 and the y-intercept is 8.

Linear equations are written like "y=mx + b"

"m" stands for slope.

"b" stands for y-intercept.

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
