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

slope 3/2, y-intercept 4

Question

Write an equation in point-slope form, slope-intercept form, and standard from for these conditions.

slope 3/2, y-intercept 4

luigi0210 · Answer

Point slope:
$$y-y_{1}=m(x-x_{1})$$

Standard form:
$$Ax+By=C$$

Slope Intercept form:
$$y=mx+b$$

luigi0210 · Answer

m=slope
x1=x coordinate 
y1=y coordinate

anonymous · Answer

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

luigi0210 · Answer

y-intercept is when x=0

luigi0210 · Answer

So (0, 4)

anonymous · Answer

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

anonymous · Answer

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

luigi0210 · Answer

Yup

anonymous · Answer

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

luigi0210 · Answer

Yup

anonymous · Answer

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

luigi0210 · Answer

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

anonymous · Answer

so A should = 1? 

3/2 x 2/3= 6/6=1?

luigi0210 · Answer

Yup!

anonymous · Answer

thanks man :D
