Find an equation of the line: through the point (2, 7.5) with an x-intercept of −1.

First you find the slope with the 2 points: (2, 7.5) and (-1, 0)

y1-y2/x1-x2 so  7.5-0/2-(-1) which equals 2.5

Next you solve the slope intercept form equation to get b

y=m*x+b (m is the slope and b is the intercept)

7.5=2.5*2+b

b=2.5

So the equation is y=2.5x+2.5

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9

step-by-step explanation:

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
