Step-by-step explanation:
Add them all up 15 if one is taken out and no replaced OR put back in, then the second draw will have 14 beads.
4 x 6 = 24
15 x 14 = 210
What is the equation of a line that goes through the point (0, -5) and has a slope of -3?
2 answers:
Answer:
y = -3x - 5
Step-by-step explanation:
The equation of a line is given as either:
where m is the slope, and b is the y-intercept.
or
where given that you have a point (x, y), y₁ is the y-value of the point, m is the slope, and x₁ is the x-value of the point.
We can just plug in the point (0, -5) into the second equation and -3 for the slope.
<em>However,</em> (0, -5) tells us that this point must be a <u>y-intercept</u>, since the x-value of that point is 0. So, we can also just plug into the first equation -5 for the y-intercept and -3 for the slope.
So, we get:
y = -3x + (-5)
Which simplifies into:
y = -3x - 5
