Graph the equation and identify the 3 Graph the equation and identify the
y-intercept. I y-intercept.
3” X: ‘ 2 ' X + y = — 5 Use the graphing tool on the right to graph the .. . . . Plotting three points helps avoid mistakes. A
equation ' ' . . . The ﬁrst two points will determine the line, I3- and the third should eliminate mistakes.
Eli-1 First solve for y by writing an equivalent
equation in the form y=mX+ b. : 9%-
—|- :—'—'a Tie y-intercept is :(D -- ' (Type an ordered pair.) Add , X to both Sides. v=-x-5 Now, ﬁnd the v-coordinate for a given X'by
substitution. Replace X with the given value
and solve the equation. The ﬁrst value for X is - 3. Substitute this
value into the equation and solve for y. Questlon Is complete. Y: _ (_ 3) _5 "Span-Ir. showing Plot the point (- 3, - 2). The next value for x is 3. Substitute 3 for x
in the equation. Plot the point (3, - 8) Aﬁer plotting both points, graph the line as
shown on the right. . Question is complete. ...
