F(x)=-1x-1
1) Pick 2 points on the line (i chose (-4,3) and (3,-4)
2) Find slope of the line using the 2 points. (work below)
3) Find y-intercept, which is the point where y-axis and the line cross (y-intercept is -1).
4) Place both slope and y-intercept into slope-intercept form, y=mx+b (m=slope and b=y-intercept.)
5) Change y to f(x) (meaning function of x).
Work:
3-(-4)/-4-3=3+4/-4-3=7/-7=-1
y-intercept equals -1 also.
y=mx+b
y=-1x+(-1)
y=-1x-1
f(x)=-1x-1<---Answer
It is easy to go to tiger math and type that in
Answer:
eq of line is x=3 and slope is infinite
If you would like to know which is the most reasonable goal for Kirk and his family to plan to save, you can calculate this using the following steps:
a. $225 a month * 2 years * 12 months = 225 * 2 * 12 = $5400
b. $200 a month * 3 years * 12 months = 200 * 3 * 12 = $7200
c. $100 a month * 4 years * 12 months = 100 * 4 * 12 = $4800
d. $75 a month * 5 years * 12 months = 75 * 5 * 12 = $4500
The most reasonable goal to plan to save would be goal b, because $7200 is more than <span>$6845.</span>
