Question

Write an equation in point-slope form, slope-intercept form, and standard from for these conditions.

slope 3/2, y-intercept 4

Answer 1

Point slope:
\[y-y_{1}=m(x-x_{1})\]

Standard form:
\[Ax+By=C\]

Slope Intercept form:
\[y=mx+b\]

Answer 2

m=slope
x1=x coordinate
y1=y coordinate

Answer 3

i know the formula's but how do you start when your given a y-intercept rather then an ordered pair??

Answer 4

y-intercept is when x=0

Answer 5

So (0, 4)

Answer 6

oh okay so then i do y-4=3/2(x-0)

Answer 7

is this correct for point slope y-4=3/2(x-0)

Answer 8

Yup

Answer 9

then for slope-intercept Form y=3/2x+4

Answer 10

Yup

Answer 11

then for standard form its 3/2x+y=4 A=3/2 B=1 C=4

Answer 12

You can't have a fraction in front of the A, so multiply it by it's reciprocal

Answer 13

so A should = 1?

3/2 x 2/3= 6/6=1?

Answer 14

Yup!

Answer 15

thanks man :D

Answer 16

Anytime :)
