Question

mehek14 · Answer

slope formula

$\dfrac{y_2-y_1}{x_2-x_1}$

$\dfrac{30-22}{14-4}$

mehek14 · Answer

simplify that

mehek14 · Answer

so slope is $\dfrac{4}{5}$

mehek14 · Answer

for the second question...where does it talk about grace?

mehek14 · Answer

oh ye
what was the equation for that lol
i forgot

mehek14 · Answer

so what is greater:

$\dfrac{4}{5}$ or $\dfrac{3}{4}$?

mehek14 · Answer

ye that's correct

mehek14 · Answer

point-slope

$y-y_1=m(x-x_1)$

slope-intercept

$y-mx+b$

mehek14 · Answer

im not good with point-slope

but slope intercept: find slope and y-intercept
slope = 4/5
y = 4/5x + b
22 = 4/5 * 4 + b
18.8 = b

so slope-intercept is
y = 4/5x + b

mehek14 · Answer

point-slope

y - 22 = 4/5(x-4)

$y-22=\dfrac{4}{5}x-3.2$

from the examples I saw, you move everything to one side and the other side is set to 0

$\dfrac{-4}{5}x+y-18.8=0$

mehek14 · Answer

and then you solve for y to get slope-intercept, which we already got

mehek14 · Answer

solve for y and you get


y = 4/5x + b

mehek14 · Answer

wait

y = 4/5x + 18.8

mehek14 · Answer

and for the last one, the answer is the y-intercept or 18.8
