y=3(0)β2=β2
y=3(1)β2=1
y=3(2)β2=4
Users' Answers & CommentsPlot the graph of π¦=π₯+2 using the points (-2, 0), (-1, 1), (0, 2), (1, 3), (2, 4).
Plot each point and draw a line through them.
The graph is a straight line passing through the points (-2, 0), (-1, 1), (0, 2), (1, 3), (2, 4).
Users' Answers & CommentsWhat is the slope and y-intercept of the line π¦=4π₯β1?
The equation is in the form
π¦=ππ₯+π, where
π is the slope and
π is the y-intercept.
Slope π=4, y-intercept π=β1.
