If a line with a slope of -2 crosses the y-axis at (0, 3), what is the equation of the line?


y − 2x = 3



-2y + 3x = 1



y + 3x = 2



y + 2x = 3

b=3

helpkay · Answer

ok to graph I math way https://mathway.com/graph

helpkay · Answer

remember it has to cross at 0, 3

helpkay · Answer

but first we need to change it to y=mx+b

helpkay · Answer

ok great :)

helpkay · Answer

what is your answer

helpkay · Answer

sorry I taged the wrong person @FaiqRaees

faiqraees · Answer

The equation of the line is 
y = slope *x + y intercept
Slope = -2
y = -2x + y intercept
y intercept = 3
y = -2x +3
y+2x = 3
There you go the answer is D
