Question

The line that passes through (1, 5) and (-2, 3) in standard form

Answer 1

"standard form" ? Do you mean Ax + By = C ?

Anyways, so first find the slope, M = y2-y1/x2-x1

M = 3-5 / -2 - 1
M = -2 / -3

So your slope is 2/3

Now plug in y-y1=M(x-x1)


y - 5 = 2/3(x-1)
y - 5 = 2/3x - 0.666
+5 +5

y = 2/3x + 4.33

I don't know what you mean by standard form

Answer 2

That is standard form @tHe_FiZiCx99 .

Answer 3

Input in standard form the equation of the given line.

The line that passes through (1, 5) and (-2, 3)
that was the question I was given..

Answer 4

Okay, first off. Find the slope of the two pairs of coordinates.
\[slope = m = \frac{ y_2-y_1 }{ x_2-x_1 }\]
\[m = \frac{ 3-5 }{ -2-1 } = \frac{ -2 }{ -3 } = \frac{ 2 }{ 3 }\]
Then use the formula
\[y - y_1 = m(x-x_1)\]

Answer 5

\[y - 5 = \frac{ 2(x-1) }{ 3 }\]
Multiply both sides by 3.
\[3y - 15 = 2x - 2\]
Change to standard form of
\[ax +by = c\]
\[-2x+ 3y = 13\]

Answer 6

Find the slope of the line whose equation is 7y = 3x + 1

Answer 7

7y = 3x +1
Remember the formula for slope-intercept is:
\[y = mx + b\]
where m = slope
So, isolate y.
\[\frac{ 7y }{ 7 } = \frac{ 3x }{ 7 } + \frac{ 3 }{ 7 }\]
\[y = \frac{ 3 }{ 7 } x + \frac{ 3 }{ 7 }\]
So slope = m = 3/7

Answer 8

John made a rectangle pen for his dog using 28 feet of fencing. If the width of the pen is 2 feet more than one-half the length, what is the length and width of the pen?
The length of the pen is

Answer 9

Rectangle perimeter = 28 ft
width = 2 + 1/2(L)

Perimeter = 2L + 2W
so

28 = 2L + 2(2+1/2(L))
28 = 2L + 4 + L
24 = 3L
8 = L

W = 2 + (1/2)L
W = 2 + (1/2)8
W = 2 + 4
W = 6

Answer 10

Find the slope of the line passing through the points (3, 8) and (-2, 5)

Answer 11

Use the slope formula I posted above.

Answer 12

I did.. I got .6 & that's not an answer on my choices..

Answer 13

.6 = 6/10 = 3/5

Answer 14

Oh, lol. I feel so dumb!

Answer 15

2x+y=7
5x+y=9
Solve the system of equations

Answer 16

y = -2x + 7

5x + (-2x +7) = 9
3x = 2
x= 2/3

y = -2(2/3) + 7
y = -4/3 + 7
y = -4/3 + 21/3
y = 17/3
