Question

Part a.) Find the slope of the line that contains the points, (1, 2) and (2, 5). (5 points)

Part b.) Using the slope that you found in part a and one of the given points, write the equation of the line. Please write your final answer in slope-intercept form. (5 points)

Answer 1

please help

Answer 2

To find the slope you need to do \[m=\\[m=\frac{ y _{2}-y _{1} }{ x _{2}-x _{1} }\]]
Just plug in the two coordinates you have
\[m=\frac{ 5-2 }{ 2-1 }\]

Answer 3

What did you get for slope?

Answer 4

m=3

Answer 5

Good job. Now plug in what you got for slope into the equation to get y=3x+b
Use one of the coordinates to find the value of b
\[2=3*1+b\]

Answer 6

^this is for part b

Answer 7

i got it thank you
