Question

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

Answer 1

@Nnesha do you know?

Answer 2

okay so here is a equation y = mx + b
where m is slope and b is y-intercept
so replace m by -2

Answer 3

your y-intercept at (0,3)
where x is zero
so y-intercept is 3
point on y-axis is y-intercept

Answer 4

You already have the slope and the y-intercept. Thus the equation of a line in slope intercept form is

y = (slope)x + y-intercept

Answer 5

y − 2x = 3
-2y + 3x = 1
y + 3x = 2
y + 2x = 3
Those are my options there not in the same form

Answer 6

option are in standard form
so what is your equation should be with -2 slope and 3 y-intercept

Answer 7

y=-2x+3?

Answer 8

yes now add 2x both side

Answer 9

would it be y+2x=3?

Answer 10

yes right

Answer 11

David is rowing a boat upstream. The river is flowing at a speed of 2 miles per hour. David starts rowing at a speed of 6 miles per hour, and his speed decreases at a rate of 1.5 miles per hour.
which equation gives the speed of the boat after David has rowed for x hours
A.Y=4+1.5X
B.Y=4-1.5X
C.6-1.5X
