With even just two points, you can find the equation of a line in slope-intercept form.
Slope-intercept form:
where
is the slope and
is the y-intercept
<u>1) Solve for the slope (</u>
<u>)</u>
The equation to solve for the slope is
when the two points are
and
. Plug the coordinates of these points into the equation and solve for
.
Then, plug
into
.
<u>1) Solve for the y-intercept (</u>
<u>)</u>
Then, take any of the given points and plug it into
along with the slope. Isolate
to get the y-intercept. Then, plug both m and b back into
to get your final equation.
I hope this helps!
Answer
The Answer is A C D
Step-by-step explanation:
Answer:
y=-3/4-5
Step-by-step explanation:
plug in ordered pair 1= -3/4(-8)+b
solve for b. b= -5
plug in to y=mx+b
Answer:
Question 6: the slope is 3
Question 7: 5
Question 8: y=3x+5
Step-by-step explanation:
Using rise over run, You can see that it is 3 in rise and 1 in rise. 3/1 is 3. The y-int is 5 because that is where it touches the y-axis. The formula is y=mx+b where m is slope and b is y-int. Sub the other answers in to find the answer. Hope this helps! Pls mark brainliest!
