Aline passes through the point (10, -9) and has a slope of - 1/2. write an equation in slope intercept form for this line.

Point Slope intercept form:

The equation of the straight line is given by;

                   ......[1]

where

m represents the slope of a line.

As per the given statement:

Substitute these given values in [1] we have;

or

Using distributive property;

Subtract 9 from both sides we get;

Therefore, the equation in slope intercept form(i.e y=mx+b) is,

4 adults and 12 babies

step-by-step explanation:

4 x 7 = 28

12 x 15 = 180

180 + 28 =208

4 x 3 = 12
