Point-slope form of a line: We need a point (x₀,y₀) and the slope "m";
y-y₀=m(x-x₀)
We have the next equation of line:
y=1/2 x-2 (slope-intercept form y=mx+b)
the slope of this line is 1/2 (m=1/2)
And any one point could be:
if x=0; then y=1/2 (0)-2=-2 (0,-2)
Therefore, we already have the point (0-,2) and the slope (m=1/2)
y-y₀=m(x-x₀)
y+2=1/2(x-0)
Answer: the point slope form of y=1/2 x-2; would be:
y+2=1/2(x-0)
35x5=175
175x1=175
25x7=175
Slope is -3
Explanation
Take points
(4,3) and (6,-3)
-3-(3)
———= -6/2 which equals -3
6-4
I know that the first one is the (sum) of a number x and 8.1 but im not sure about the rest im sorry
The answer is $36.22 because you need to times 21.95 by 0.65 and you get 14.27 and add that to the original price.
