Question

Use the information given to enter an equation in standard form. Slope is 3, and (2, 7) is on the line.

Answer 1

Answer:  $y-3x=1$

Step-by-step explanation:

Standard form :

Ax+By=C

We have a linear function y=kx+b ;

we also know its slope k=3 ; and that it passes through the point (2 ; 7 )

Then:

$y=3x+1$

now substitute the knowledge of the coordinates of the point

$3\cdot 2+b=7 \\\\ b=7-6\\\\ \underline{b=1\ \ \ \ \ }$

Then we get the function:

$y=3x+1$

Standard form :

$y-3x=1$

Answer 2

Answer:

3x - y = -1

Step-by-step explanation:

Standard form of equation is Ax + By = C

y - y1 = m (x -x1)

y - 7 = 3 (x - 2)

y - 7 = 3x - 6

3x - y = -7 +6

3x - y = -1
