Write the equation of the line that passes through (1, 3) and (4, 4) in standard form.
What is the slope?
\[slope=\frac{y-y_1}{x-x_1}\]
Isn't standard form A+B=C. While y= mx+b slope intercept form?
oh yeah, your right!!
Well just find the equation. You can put it in the correct form after you know what it is.
What is the slope?
Y=MX+B
slope = change in y over change in x
Subtract the y values of the ordered pairs. Subtract the x values of the ordered pairs. Make a fraction out of your answers.
4 - 3 = 1 (y coordinate), 4 - 1 = 3 (x coordinate) y = 1/3x + b <---- slope intercept form (plug one of the coordinates in to solve for y intercept): 3 = 1/3(1) + b -1/3 -1/3 (algebraically manipulate) b (y intercept) = 8/3 or 2 and 2/3 y = 1/3x + 8/3 or -1/3x + y = 8/3 ---> Standard form Ax + B = C (Is that right, Mertsj?)
4-3=1 4-1=3 slope = 1/3
Yes Josh, that is right.
Great :) thanks a lot, I thought i'd forgotten
Good job.
