Aline passes through the point (-8,-7) and has a slope of 3. write an equation for the line

Answer

y = 3x + 17

Explanation

If you you want to find the equation of a line you require a point on that line and is gradient.

gradient = 3

a point on the line is (-8, -7)

Chose another general point (x, y)

gradient = (change in y)/(change in x)

3 = (y- -7)/(x- -8)

3 = (y+7)/(x+8)

3(x+8) = y+7

3x+24 = y+7

y = 3x + 24 - 7

y = 3x + 17

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.
