Let their ages be g and k.  Then g = k + 3.

Next:  (g+7) + (k+7) = 41.

Substituting k + 3 for g in the above equation, we get  k + 3 + 7 + k + 7 = 41.

Combining like terms:  2k + 17 = 41.  Then 2k = 24, and k = 12.

Kevin is 12 years old and Greg is 15 years.

Use point slope form to write the lines with the given slope and point in slope intercept form.m= -1(-5,-4)
lara31 [8.8K]

The slope point form is

y-y1=m(x-x1)

m is the slope

x1, y1 are the coordinates of a point on the line

The slope of the line is -1

m = -1

point (-5, -4) lies on the line

x1 = -5 and y1 = -4

Let us substitute them in the form above

y-(-4)=-1(x-\lbrack-5\rbrack)

Remember (-)(-) = (+)

y+4=-1(x+5)

The equation of the line in the slope-point form is y + 4 = -1(x + 5)
