Answer:
y= -1/4x - 6
Step-by-step explanation:
So the point slop form is y = mx + b, where m is the slope : -1/4, and b is the y-intercept (which we don't know yet).
To find b, all you need to do is plug in -1/4 for m and the point (4, -7) for x and y respectively, giving you:
-7 = (-1/4)(4) + b
Then do some algebra shenanigans: multiply -1/4 by 4 to get -1
-7 = -1 + b
then add the 1 to both sides.
b = -6
Then, you can plug the b and the m back into the problem to give you:
y = -1/4x - 6
Answer:
C
Step-by-step explanation:
Point slope form looks like this: [tex]y-y_1=m(x-x_1)[/tex]
We already have our slope (-1/4)
Our [tex]y_1[/tex] is -7 and our [tex]x_1[/tex] is 4
In this case, our equation would be [tex]y-(-7)=-1/4(x-4)[/tex] and the -(-7) would turn into +7
Therefore, the answer is C
