Question

The line of best fit for a scatterplot is shown what is the equation of this line of best fit in slope intercept form?

(pic provided)
1. y=-6x+3/4
2.y=6x+3/4
3. y=-3/4x+6
4. y=3/4x+6

Answer 1

y=-3/4x+6

Explanation:

the y/intercept is (0,6) because that is the point where the line crosses the y-axis

knowing that use the point (0,6) and (4,3) to find the slope use rise over run so it goes up 3 and right 4

using the slope intercept equation y=mx+b it is y= -3/4+6

it is negative because its going downward

hope this makes sense and helps you guys!

Answer 2

3. y=-3/4+6

Explanation:

The y-int is 6, so you can already cross out the first two answers. Then, you know the slope is negative because the line is going downward, so -3/4 has to be the slope bc it is negative.
