Question

chin was shown the graph of a line that contained point (1,7). he wrote f(x)= 4x+3 to correctly represent the line. which of these equation could be represent the same line. A. y-7=3(x-1). B. y-1=3(x-7) c. y-7=4(x-1) D. y-1=4(x-7)

Answer 1

the answer is C. Hope this Helps

Answer 2

Answer:

c. y-7=4(x-1)

Explanation:

The function Chin wrote, f(x) = 4x+3, is in slope-intercept form.  The slope is 4 and the y-intercept is 3.  Another form of a linear function is point-slope form,

$y-y_1=m(x-x_1)$, where (x₁, y₁) is a point on the line and m is the slope.  

For the given information, we would have

$y-7=4(x-1)$
