Write the equation 'x-intercept = 4, y-intercept = -1' in slope-intercept form.

y = 1/4x-1

Step-by-step explanation:

The slope intercept form of a line is

y = mx+b

m is the slope and b is the y intercept

but we do not know the slope y know the x intercept

(4,0 )

and  the y intercept

( 0,-1)

We can calculate the slope  using these points

m = (y2-y1)/ (x2-x1)

   = (-1-0)/(0-4)

    = -1/-4

    = 1/4

Now we can put the slope = 1/4 and the y intercept =-1 into the formula

y = 1/4x-1

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
