Answer:
Jim + June + Alex = 82 (x+9) x + (x-8) = 82 3x +1 = 82 3x = 82 - 1 = 81 x = 81/3 = 27. ANSWER. June is 27 years old; Jim is 27+9 = 36 years old; Alex is 27-8 = 19 years old.
Answer:
The equation of the line is 4y = -x + 19
Step-by-step explanation:
Firstly, we need to get the slope of the line;
Since it is through two points; we have the slope as;
y2-y1/x2-x1 = (5-3)/(-1-7) = 2/-8 = -1/4
Mathematically, we can write the equation of a straight line line as;
y = mx + c
So we have;
y = -1/4x + c
y = -x/4 + c
To complete the equation, we need the value of c.
we can choose any of the points and insert the x and y value
Thus;
3 = -7/4 + c
c = 3 + 7/4
c = 19/4
So our equation becomes;
y = -x/4 + 19/4
Multiply through by 4
4y = -x + 19
