Find an equation of the line through these points (15,2.2) (5,1.6). Write answer in a slope-intercept form

Step-by-step explanation:

Hi there!

Slope-intercept form: where is the slope and is the y-intercept (the value of y when x is 0)

1) Determine the slope (m)

where two given points are and

Plug in the given points (15,2.2) and (5,1.6):

Therefore, the slope of the line is . Plug this into :

2) Determine the y-intercept (b)

Plug in a given point and solve for b:

Therefore, the y-intercept is . Plug this back into :

I hope this helps!
