Question

PLEASE HELP!!!!!!!!!!!!!


Find the equation of a line with the given points. (Put your answers in the form y = mx + b.)

(7, 2)
(5, 4)
PLEASE GIVE THE EXACT ANSWER

Answer 1

Can you find the slope?

Answer 2

Find the slope m and use one of the points, say <7,2>, and solve y=mx + b for the y-intercept, b:
$$
2=\cfrac{4-2}{5-7}\times7+b\\
b=2-\cfrac{4-2}{5-7}\times7\\
$$
Where
$$
m=\cfrac{4-2}{5-7}
$$
Once you have b and m put into the following equation:
$$
y=mx+b
$$
