Which linear equation best represents the line of best fit for the scatterplot?

Mathematics

Lena [83]2 years ago

Answer:

y = -\frac{1}{3}x

Step-by-step explanation:

The scatter plot trends downward from left-> right, meaning that it is negative. Next, use two points to solve for the value for the slope.

In this case, I will use (-3 , 1) & (0 , 0)

Use the following equation. m = slope:

m = \frac{y_2 - y_1}{x_2 - x_1}

Let:

(x_1 , y_1) = (0 , 0)\\(x_2 , y_2) = (-3 , 1)

Plug in the corresponding numbers to the corresponding variables:

m = \frac{1 - 0}{-3 - 0} = \frac{1}{-3} = -\frac{1}{3}

Your answer will be:

y = -\frac{1}{3}x

Which graph represents y=1/2x+2 <br><br> please help!!
wel

Answer:

B

Step-by-step explanation:

Let’s first look at the y-intercept. Since the equation is in y = mx + b form, we know that m is the slope and b is the y-intercept, so the slope is 1/2 and the y-intercept is 2, or (0,2). We can narrow down our search by noticing that C and D don’t intersect (0,2). That leaves A and B.

The slope is calculated by (y_1 - y_2)/(x_1 - x_2) given points (x_1, y_1) and (x_2, y_2). The slope for A is (4-0)/(2-(-2)) = 4/4 = 1 and the slope for B is (2-0)/(0-(-4)) = 2/4 = 1/2. The slope of B matches the slope that we are looking for. So, the answer is B.
