Which equation represents a line that passes through (2,-1/2) and has a slope of 3?
y-2 = 3(x + 1)
y-3= 2x+5
y+ 4 = 3(x-2)
y+ 1 = 2(x - 3)

Step-by-step explanation:

Since both a point on this new line and the slope of the line are given, we use the "point-slope equation of a straight line," that is, y - k = m(x - h).  

Here we are told that the point is (2, -1/2), so h = 2 and k = -1/2.  

The slope, m, is 3.  Thus,

y - k = m(x - k) becomes y + 1/2 = 3(x - 2)

Check:  does the point (2, -1/2) satisfy this equation?

Is -1/2 + 1/2 = 3(2 - 2)?  Yes.  So this equation must be correct.  Please ensure that you have copied down all of the possible answers correctly.

62.5 paisa

step-by-step explanation:

4000*70 = 280000

280000-(2000*90) = 100000

4000-2400 = 1600

100000/1600 = 62.5

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
