Question

HELP ....... write standard form using these points (2,3), (-1,5)

Answer 1

what standard form ?

Answer 2

ax+by=c

Answer 3

and this is a standard form of ?

Answer 4

slope

Answer 5

I'm going to assume that you want to make a line of those two points.

First, find the slope.

3-5 / 2-(-1)
-2/5

Next, plug in the points.

y – y1 = m(x – x1)
y-3=-0.4(x-2)
y-3=-0.4x+0.8
y+0.4x=3.8

Then multiply by 2.5 to make it look pretty.
x+2.5y=9.5

Answer 6

Incorrect,try again :)

Answer 7

\[ m = \frac{3-5}{2-(-1)} \]
\[ m = -\frac{2}{3} \]

\[ y - y_1 = m(x- x_1) \]
\[ y - 3 = -\frac{2}{3}(x- 2) \]
\[ y = -\frac{2}{3}(x- 2) + 3\]
\[ y = -\frac{2}{3}x + \frac{4}{3} + 3\]
\[ y = -\frac{2}{3}x + \frac{13}{3} \]

Answer 8

oh in standard form
it'll be

\[\frac{2}{3}x + y = \frac{13}{3}\]

multiply both sides by 3
\[2x + 3y = 13\]
