Question

Write the equation of the line with slope –4 and y-intercept (0, –6).
A) y = –6x – 4
B) –6x – 4y = 0
C) y = –4x – 6
D) –4y = –6

Answer 1

The answer is y = - 4x - 6 (C)

Answer 2

The answer is C because:

the equation for a line is y=mx+b

m=slope
x=equals the independent variable
b= y intercept

therefore if the slope is -4, the m must equal -4:

Equation so far: y= -4x+b

The coordinate (0,-6) has -6 as the y value and since x=0, that is the point that it intercepts the y-axis. So b= -6

Therefore the equation is

y=-4x-6

Answer 3

the answer is C because:
the slope (-4) always goes in front of the x and when you set up the equation of the line its:
y = (slope)x + y-intercept
so....
y = -4x - 6
Its (minus) 6 because the y-intercept is negative 6 on the point (0, -6)
Hope this helps!

Answer 4

y=mx+c minus y factors from one yet another and minus x factors from one yet another 3--3=6 0--6=6 gradient is upward thrust(y) over run(x) so the gradient is 6 / 6 or a million . so which you write a million particularly of m c is the y intercept to discover that put in one set of your many times happening factors i will use (3,0) and you already be attentive to m is a million so 0 = 3 +c c= -3 so the equation of your line is y=x-3 (you do no longer ought to write down the a million)

Answer 5

the answer is c

the basic equation of the line is y=mx+b where m is the slope and b is the y-intercept. (simple right?)

well in your scenario, since it states that the slope is -4, you know that the equation so far is y= -4x+b

and since the coordinates for the y-intercept is given, the final answer is y= -4x+b

Answer 6

C because y=mx+b
b=y intercept so -6
m= slope -4
put it al togther and y=-2x+(-6) or y=-2x-6

Answer 7

c
