1 answer:
Answer:
The corresponding set of values of the dependent set is: {-5, -7, 0}
Step-by-step explanation:
Dependent variable and independent variable:
Suppose we have a function f(x).
The independent variable is the input value of the function, that is, x.
The dependent variable is the output value of the function, that is, f(x).
The replacement set for the independent variable is (-1, -2, 1,5).
The values of the dependent set are respectively, f(-1), f(-2) and f(1.5). So
We have that: . So
The corresponding set of values of the dependent set is: {-5, -7, 0}

Answer:
The equation in the slope-intercept form will be:
y = 1/4x - 7
Step-by-step explanation:
Given the points
- (-4.-8)
- (-8, -9)
We know that the slope-intercept of line equation is
where m is the slope and b is the y-intercept
substituting m = 1/4 and the point (-4, -8) to find the y-intercept 'b'
y = mx+b
-8 = 1/4(-4)+b
-8 = -1 + b
b = -8+1
b = -7
so the y-intercept = b = -7
substituting m = 1/4 and b = -7 in the slope-intercept form of line equation
y = mx+b
y = 1/4x + (-7)
y = 1/4x - 7
Thus, the the equation in slope-intercept form will be:
y = 1/4x - 7
