Sagot :
y=-1/4x+8
First find the slope
Slope= y-y1/x-x1
So (6-7)/(8-4) = -1/4
Now take that slope and use one of the points and plug them into the point slope formula to solve for your y intercept.
Point slope formula: y=mx+b
So 7=-1/4(4)+b OR 6=-1/4(8)+b
Either way you’ll get b=8!
Put em together and you get: y=-1/4x+8
Ps you can double check your answer by plugging in one or both of the points into your equation to see if it works :)

Answer:
y - 7 = [tex]-\frac{1}{4}[/tex] (x - 4)
Step-by-step explanation:
Find Slope: m = [tex]\frac{y_{2-}y_{1} }{x_{2-}x_{1} }[/tex]
m = [tex]\frac{6-(7)}{8-(4)}[/tex]
m = [tex]\frac{-1}{4}[/tex]
Point Slope Form: y - [tex]y_{1}[/tex] = m ( x - [tex]x_{1}[/tex] )
y - 7 = [tex]-\frac{1}{4}[/tex] (x - 4)
