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

y − 2x = 3

-2y + 3x = 1

y + 3x = 2

y + 2x = 3

Answer 2

Answer 3

y = mx + b
slope(m) = -2
(0,3)...x = 0 and y = 3
now we sub
3 = -2(0) + b
3 = b

so your equation is : y = -2x + 3
but we need it in standard form Ax + By = C
y = -2x + 3 -- add 2x to both sides
2x + y = 3 (answer D)

Answer 4

y = mx + b

Where m = slope(in this case -2), and where b = the y-intercept(in this case 3)
