What is the equation of the function that is graphed as line a?
valentinak56 [21]
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

Answer:

(5y-2)x(2x+5)

Step by step explanation:

10xy-4x+25y-10

Factor out 2x from the expression

2x*(5y-2)+25y-10

Factor our 5 from the expression

2x*(5y-2)+5(5y-2)

Factor out 5y-2 from the expression

(5y-2)x(2x+5)
