Write the slope intercept form of the equation of the line through (2,1) and (4,5)
​

Step-by-step explanation:

Hi there!

Slope-intercept form: where m is the slope and b is the y-intercept (the value of y when the line crosses the y-axis)

1) Determine the slope (m)

where the two given points are and

Plug in the given points (2,1) and (4,5)

Therefore, the slope of the line is 2. Plug this into :

2) Determine the y-intercept (b)

Plug in one of the given points and isolate b

Subtract both sides by 4

Therefore, the y-intercept of the line is -3. Plug this into :

I hope this helps!
