Question

The slope of a line is -, and the y-intercept is 10/3. What is the equation of the line written in general form?



A) 10x + 3y - 1 = 0

B) x + 3y + 10 = 0

C) x + 3y - 10 = 0

Answer 1

y=-1/5x +10/3

Answer 2

is it A?

Answer 3

Have you seen the Slope-Intercept Form?

Answer 4

slope is - what??
suppose to be -1/5

Answer 5

right?

Answer 6

yeah

Answer 7

Answer is C

Answer 8

YOu cannot determine the slope with the info given. Put each equation in the form y=mx+b...

Answer 9

Follow y=mx+c, y=x/3+10/3

Answer 10

c = y intercept.

Answer 11

=> y=-1/5 x +10/3

Answer 12

For A & B, the y intercept is not 10/3.

Answer 13

Anytime you are given the slope (or a hint about the slope) and the y-intercept, the Slope-Intercept is normally the way to go.

A) 10x + 3y - 1 = 0
B) x + 3y + 10 = 0
C) x + 3y - 10 = 0

Move the constant with subtraction.

A) 10x + 3y = 1
B) x + 3y = -10
C) x + 3y = 10

Move the x-term with subtraction.

A) 3y = -10 x + 1
B) 3y = -x - 10
C) 3y = -x + 10

Isolate the the 'y' and produce the final Slope-Intercept Form.

A) y = -(10/3) x + 1/3
B) y = -(1/3)x - 10/3
C) y = -(1/3)x + 10/3

Identify the parts

A) y = -(10/3) x + 1/3 <== Slope: -10/3 and y-intercept 1/3
B) y = -(1/3)x - 10/3 <== Slope: -1/3 and y-intercept -10/3
C) y = -(1/3)x + 10/3 <== Slope: -1/3 and y-intercept 10/3
