What is an equation of the line that passes through the points (4, 4) and (8, 1)?
1 answer:
Answer: y = -3/4x + 7
Step-by-step explanation:
first find slope:
y2-y1 / x2 - x1
1-4 / 8-4
-3/4
now just plug the slope (m) into the equation of a line using one of the points to find the y intercept
ill use (8,1)
1 = (-3/4)(8) + b
now solve :)
1 = -6 + b
7 = b
so now plug in the slope and the y intercept into the slope intercept form to find the equation of the line
y = -3/4x + 7
