Question

Find the equation of the line having the given slope and containing the given point.
m=7/8, (7,-2)
The equation of the line is y=

Answer 1

IMPORTANT LINE RELATED EQUATIONS TO KNOW AND MEMORIZE

slope formula
m= slope/ gradiant -- same thing
\[m=\frac{y_2-y_1}{x_2-x_1}\]

standard formula
\[Ax+By=C\]

point-slope formula
\[y-y_1=m(x-x_1)\]

slope-intercept formula
b= y-intercept -- in the form of (0,y)

\[y=mx+b\]

Answer 2

Which formula would it be?

Answer 3

Point-Slope one!

Answer 4

How would I write this in slope-intercept form?

Answer 5

Do you have slope m yet?

Answer 6

BTW, are you sure you read my instruction correctly?

Answer 7

It told e to simplify answer and type it in slope-intercept form

Answer 8

INPUT YOUR VALUES INTO THE POINTSLOPE FORM THEN SIMPLIFY AND CONVERT TO SLOPE INTERCEPT FORM

Answer 9

@jmallis Can you start with plugging the values into point-slope form?

Answer 10

y=7/8x+(7,2) ?

Answer 11

Where do you get 7.2 ???

Answer 12

(7,-2)

Answer 13

Oh, (7, -2) means x = 7, y -2

Answer 14

Now can you replug the values in?

Answer 15

so y=7/8(7)+(-2)

Answer 16

@jmallis you have huge problem with following the instruction, do you (Sighs)
You can't go directly to point intercept without knowing y intercept,
so you need 2 steps: first write in Point-Slope form, then simplify it into Slope-Intercept!

Answer 17

Point-Slope:
y +2 = (7/8) ( x - 7)
Now distribute 7/8 in, simplify it into Slope-intercept form!
