Answer: y = -2x + 4

Step-by-step explanation:

First, you can find b (the y-intercept) from the coodinates. Where y=0, x=4. This is your y intercept (b).

To find the slope (m), take two points from the graph:

Let's use (2,4) and (3,2). Next, find the difference in the x and y values.

Difference in Y = 4-2 = 2

Difference in X = 2 - 3 = -1

Now we can find the slope by dividing the difference in y values by the difference in x values:

2/-1 = -2 (m = -2)

Now plug the values for b and m into your equation.

y = -2x + 4

The distance AB rounded to the nearest tenth = [ ? ]
docker41 [41]

Answer:

4.5 units

Step-by-step explanation:

To get the distance we need the coordinates of the points

A is ( 3,1)

B is (-1,-1)

Let A be (x1,y1) and B be (x2,y2)

So applying the formula, we have the distance as;

D = √(-1-3)^2 + (-1-1)^2

D = √(16 + 4)

D = √20

D = 4.5 units

Which is the approximate measure of this angle A. 30 b. 90 c 120 d 180
statuscvo [17]

Answer:

Answer is A. 30 degree

as we know that two prependicular lines have 90 degree angle between them

and similarly a horizontal line has angle zero degree.

the angle of pic shown is approximately 30 degree as it lies between prependicular and horizontal nature of lines

but as we can see that it is close to horizontal nature of the line that's why its approximate angle is 30 degree.
