Answer:
y=-6x+8
Explanation:
Slope-intercept form is y=mx+b, where m is the slope and b is the y intercept.
We know a point (2,-4) and a slope -6.
We can subtsitute what we know into the equation above, to find what the y intercept is, since the line will pass through the point given.
-4=-6(2)+b
multiply
-4=-12+b
add 12 to both sides
8=b
the y intercept is (0,8)
Now we know what b is, so we know what the full equation is:
y=-6x+8
hope this helps!
