A line passes through the points (1, 2) and (3, 1). What is the slope of the line? O
0-1
O2
0-2

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

Slope of the line using points

(1, 2) and (3, 1) is

Slope = 1-2/3-1 = -1/2

Equation of the line using point (1,2)

y - 2 = -1/2(x - 1)

y - 2 = -1/2x + 1/2

y = -1/2x + 1/2 + 2

y = -1/2x + 5/2

Hope this helps you

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.

can you complete your sentence? i could !
