I need help on this whole sheet plz help

state the y-intercept and the slope of the following linear equations.

think of y=mx+b

m is the slope

b is the y-intercept

1) y=3/4x-2

slope= 3/4

y-intercept= -2

2) y= -x+3

slope= -x

y-intercept= 3

3) y=3x+5

slope=3

y-intercept=5

4) y=1/2x-5

slope= 1/2

y-intercept= -5

5) y= -2x-4

slope= -2

y-intercept= -4

6) y= -1/5x-1

slope= -1/5

y-intercept= -1

7) y=3/2x+4

slope=3/2

y-intercept=4

8) y=x+1

slope=x

y-intercept=1

9) y=2x+5

slope=2

y-intercept=5

10) y=8/5x+3

slope=8/5

y-intercept=3

11) y= -3x-4

slope= -3

y-intercept= -4

12) y= -2x-2

slope= -2

y-intercept= -2

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
