A coordinate grid with a line passing through the points (negative 2, negative 1) and (2, 0) Use the graph of the line to answer

Musya8 [376]

Answer:

The general equation for a line (written in the slope-intersect form) is:

y = f(x) = a*x + b

Such that the line is already written in function notation.

Where a is the slope, and b is the y-intersect.

If a line passes through a point (x₁, y₁) and (x₂, y₂), the slope can be written as:

y = (y₂ - y₁)/(x₂ - x₁)

We know that the line in the graph passes through the points:

(-2, -1) and (2, 0)

Then the slope of the line will be:

a = (0 - (-1))/(2 - (-2)) = 1/4

Then the function for the line will be something like:

y = f(x) = (1/4)*x + b

Now we want to find the value of b.

Because we know that this function passes through the point (2, 0), this means that:

f(2) = 0 = (1/4)*2 + b

We can solve that for b:

0 = 2/4 + b

-2/4 = b

Then the function for the line is:

y = f(x) = (1/4)*x - 2/4

Question 20 (5 points)

Advocard [28]

Answer:

D.) $V:x=1;H:y=6$

Step-by-step explanation:

The vertical intersection of the point is found by the x value. Starting at the point, move down to find the value of x. The vertical line, value x, is 1.

The horizontal intersection of point B is found by the y value. Start at the given point and move to the left to find the y value. The horizontal line, y, is 6.

$(vertical,horizontal)\\\\(x,y)\\\\(1,6)$
