Step-by-step solution

To solve the problem, we will determine the equation of a line using the point-slope form. The general formula for a line in point-slope form is:

yy1=m(xx1) y - y_1 = m(x - x_1)

Given the slope m=6 m = 6 and the point (1,4) (1, -4) , we can substitute these values into the formula:

y(4)=6(x1) y - (-4) = 6(x - 1)

Simplifying the equation, we get:

y+4=6x6 y + 4 = 6x - 6

Now, we want to express this in slope-intercept form y=mx+b y = mx + b . So, we solve for y y :

y=6x64 y = 6x - 6 - 4

Finally, combining like terms gives us the equation:

y=6x10 y = 6x - 10

Therefore, the equation that represents the function is y=6x10 y = 6x - 10 .

The correct answer choice is:

: y=6x10 y=6x-10

Final Answer

y=6x10 y=6x-10
