Choose the equation below that represents the line passing through the point (-3, -1) with a slope of 4.
y = 4*x+11
The above solution is correct. Do you find it in your answers?
no
y - 1 = 4(x - 3) y + 1 = 4(x + 3) y - 3 = 4(x + 1) y + 3 = 4(x - 1)
Please post them, and we can compare. May be it is given in point slope form. It is the second option.
i posted what do you mean
The second option is the correct. You can check it, \[y-y_0=m(x-x_0)\] m is the slope. x0 and y0 are the coordinates of the point given ;).
thanks! can you help me on more?
Yes.
Choose the equation of the line passing through the point (2, 6) and parallel to y = -3x - 4. y = 3x - 12 y = -3x y = -3x + 12 y = 3x
If it is parallel, it must have the same slope -3. And if pass through (2,6) then \[y=-3x+n\] \[6=-3\cdot2+n\Rightarrow n=12\]So, \[y=-3x+12\]
Choose the equation of the line passing through the point (6, -2) and parallel to y = x + 7. y = x + 8 y = x - 4 y = x + 4 y = x - 8
Sorry, it is the first one.
one more!! Which of the following is the slope between the points (0, -7) and (4, 12)? 19 fourths -19 fourths 4 nineteenths -4 nineteenths
The first one.
thank you john you been a big help
