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

2 answers:

6 0

General equation of the line is
y = mx + b
<span>m = 3</span>
so y=3x+b

now find b
-3=3(0)+b
-3=b

so the equation is
y = 3x - 3

3 0

General equation of the line is
y = mx + c

c = -3
m = 3

so the equation is
y = 3x - 3

When y=-15, x=-20. So subtract x from y, you will get that y= 0 and x=-5. Add 12 to both and you have your answer, x=7 and y=12

Answer:

200g of sugar, 600g of flour, 400g of butter

Step-by-step explanation:

50g sugar = 15 biscuits

3 x 50g = flour --) 150g = flour

2 x 50g = butter --) 100g = butter

60/15 = 4; 4 times as much

4 x 50g = 200g of sugar

4 x 150g = 600g of flour

4 x 100g = 400g of butter
