Which is an equation of a line that has a slope of -1/3 and passes through the point (-5, 2)?

kramer

Answer:

y= -⅓x +⅓

Step-by-step explanation:

The equation of a line is usually written in the form of y=mx+c, where m is the gradient and c is the y-intercept.

This form is also known as the point-slope form.

Since the slope is given to be -⅓, m= -⅓.

y= -⅓x +c

To find the value of c, substitute a pair of coordinates into the equation.

When x= -5, y=2,

2= -⅓(-5) +c

$2 = \frac{5}{3} + c \\ c = 2 - \frac{5}{3} \\ c = \frac{1}{3}$

Thus, the equation of the line is y= -⅓x +⅓.

Two pounds of bananas cost $1.16 what would be the cost of 5pounds s of bananas

ivann1987 [24]

If 2 lb of bananas cost $1.16, then each pound costs $0.58.

0.58 * 5 = 2.9

So 5 lb of bananas will cost $2.90.

Hope this helps!

-3/5x+-7/10+1/2x=-56

Savatey [412]

Answer:

$x=553$

Step-by-step explanation:

$\frac{-3}{5} x+\frac{-7}{10} +\frac{1}{2} x=-56$

Combine like terms:

$-\frac{1}{10} x =-\frac{553}{10}$

Multiply both sides by -10:

$x=553$
