What have you been doing for hours?
y=mx+b
6=8*-7+b
6=-56+b
62=b
So now we have the y intercept (b=62) and the slope (m=8)
y=mx+b
y=8x+62
Answer by jim_thompson5910(35256) (Show Source): You can put this solution on YOUR website!
If the slope is 8, then m = 8
If the point (-7,6) lies on the line, then x = -7 and y = 6
We can use these facts, along with the equation y = mx+b, to find the value of 'b' which will effectively give us the equation of the line
y = mx+b
y = 8x + b
6 = 8(-7) + b
6 = -56 + b
6 + 56 = b
62 = b
b = 62
So the equation of the line is
