Question

Can someone please put the solution on how you answer this in scatter plots? Y - 50 = 32.1 (x-2)

My book says the answer is y=32.1x - 14.2 so i question how we got 14.2

Answer 1

Explanation:

To answer this question, we first need to understand the equation given.

The equation Y - 50 = 32.1 (x-2) is in point-slope form, where (2, 50) is a point on the line and 32.1 is the slope of the line.

To convert this equation into slope-intercept form (y = mx + b), we need to isolate Y on one side of the equation.

Y - 50 = 32.1 (x-2)

Y = 32.1(x-2) + 50

Y = 32.1x - 64.2 + 50

Y = 32.1x - 14.2

Therefore, the equation in slope-intercept form is y = 32.1x - 14.2.

The value of -14.2 comes from simplifying the expression -64.2 + 50, which equals -14.2.
