To graph the line y=1/2x-2 you plot your first point at (0,-2) because that is your y-intercept and then you go up one and over two and plot your next point and you keep doing that until it forms a line and to go the other way you go down one left two. Hope this helps :D
If 40% or .4 of her savings is $85 then we can write the equation .4s=$85 (s being the original amount in savings)
Divide both sides by .4 to get s= $212.50 as the original amount that she had
0.1 = 1/10
1/10 of 1/10 is 1/100
1/100 = 0.01
0.01 is your answer
hope this helps
The equation of a line that passes through the point (x1,y1) and has a slope of m is
y-y1=m(x-x1)
given
slope=5
and passes throught (-2,-1) is
-2=x1
-1=y1
y-(-1)=5(x-(-2))
y+1=5(x+2)
B is answer
