Answer:
Step-by-step explanation:
an equation is : y = 10x+b
calculate b : this line passes by : (7;1) when x =7 y = 1
so : 10(7)+ b=1
b= -69
so : y = 10x-69
y = 10x - 69.
Start with the slope-intercept equation of a straight line, y = mx + b. We substitute 1 for y, 7 for x, and 10 for m, obtaining:
1 = 10(7) + b
Subtracting 70 from both sides, we get -69 = b.
Thus, the desired equation is y = 10x - 69.

I'm not positive that I know exactly what they want on this one....but since you specifically asked me to look at your other question, I tried.
