Answer:

The woman is 25, and her mother is 50.

Step-by-step explanation:

The woman is half the mother's age.

That means the mother is twice the woman's age.

Let the woman's age be x

The mother's age is 2x.

The sum of the ages is 75.

x + 2x = 75

3x = 75

x = 25

2x = 2(25) = 50

Answer: The woman is 25, and her mother is 50.

y = - 4x + - 8 is equation of slope-intercept form.

What is in slope-intercept form?

Given the slope of the line and the intercept it forms with the y-axis, one of the mathematical forms used to derive the equation of a straight line is called the slope intercept form.
Y = mx + b, where m is the slope of the straight line and b is the y-intercept, is the slope intercept form.

the equation of slope - intercept form

y = mx + c

( -1 , -4 ) is point shown in graph

slope = -y/x

= - ( -4)/-1 = 4/-1 = -4

- 4 = -4 * - 1 + c

- 4 = 4 + c

c = - 4 - 4 = - 8

put value of c in the equation of slope - intercept form

y = - 4x + - 8
