Question

Provide me three coordinate points for the following, given the Slope and Y-intercept. 5. Slope = 7/9, Y intercept = 12(give me three coordinate points)

Answer 1

Since we have that the slope is m = 7/9 and the y-intercept is b = 12, we can write the equation of the line in slope-intercept form:

`\begin{gathered} y=mx+b \\ \Rightarrow y=(7)/(9)x+12 \end{gathered}`

to find three coordinate points, we can use arbitrary values on x to get the y-coordinate. To make things easier, let's use x = 9, 18 and 27:

`\begin{gathered} x=9 \\ \Rightarrow y=(7)/(9)(9)+12=7+12=19 \\ x=18 \\ \Rightarrow y=(7)/(9)(18)+12=7(2)+12=14+12=26 \\ x=27 \\ \Rightarrow y=(7)/(9)(27)+12=7(3)+12=21+12=33 \end{gathered}`

therefore, the line with slope m = 7/9 and y-intercept 12 passes through the three points (9,19), (18,26) and (27,33)
