Answer:
Step-by-step explanation:
first find the slope with m= [tex]\frac{y2-y1}{x2-x1} \\[/tex]
M = [tex]\frac{y2-y1}{x2-x1}[/tex] = [tex]\frac{1-4}{8-4}[/tex] = [tex]\frac{-3}{4}[/tex] ← SLOPE
then add in one of the points so I am using (4, 4)
Y = mx+b
4 = [tex]\frac{-3}{4}[/tex](4)+b
4 = -3 + b
add 3 to both sides
7=b
then add those two answers into the y=mx+b formula so it would be
Y=[tex]\frac{-3}{4}[/tex] x + 7
