Answer:
It looke like the point given is (1,2) and the slope is 3
Point slope form: y - 2 = 3(x -1)
Slope Intercept form: y =
x + 1
Explanation:
Point slope As they name implies, you need a point and a slope. The picture is a little hard to read, but it looks like the point plotted is (1,2) The slope is the change in y over the change in x. It looks like from that point to get back on the line only using horizontal and vertical moves, we would move up three and 1 to the right to get back on the line at point (2,5).
The point slope form of a line is:
y -
= m( x -
) Plug in 2 for
and 1 for
amd 3 for m
y = 2 = 3( (x-1)
Slope intercept form: As the names implies we need a slope and a yi-intercept.
The slope is
. Select a point on the line. If you can only move veritacl and horizontal. You would move down 1 unit and three units to the right. The y intercept is where the line crosses the y axis. In this case 1
y =
