what is the equation in standard form of a line that passes through (1,24) and has a slope of -0.6??​
Marrrta [24]

Answer:

5y+3x=123

Step-by-step explanation:

(x1,y1)=(1,24), m=-0.6

y-y1=m(x-x1)

y-24=-0.6(x-1)

y-24=-6/10(x-1)

10(y-24)=-6(x-1)

10y-240=-6x+6

10y+6x=6+240

10y+6x=246

divide by through by 2

5y+3x=123
