Answer:

C) y = 2x + 3

Step-by-step explanation: You have to substitute 1 for x & 5 for y & 2 for m, but 1st do the point slope form ---> slope intercept form.

y -Y1 = m(x - X1)

y - 5 = 2(x - 1)

y - 5 = 2x - 2

+5 + 5

y = 2x + 3 --- IN SLOPE INTERCEPT FORM

Hope this helps you!!! :)

Answer:

4x + 2

Step-by-step explanation:

x - 1 is adding an x and subtracting a 1 ,so

x + x + x + (x - 1) + 1 + 1 + 1

= x + x + x + x - 1 + 1 + 1 + 1 ← collect like terms

= 4x + 2

What is y=\dfrac{2}{3}x+4y=

lara [203]

Answer:

$12y+x-12=0$

Step-by-step explanation:

If I'm not mistaken by the question, we have

$x+4y=\dfrac{2}{3}x+4$

Multiply through by the LCM of all the denominators to clear the fractions. Since we have only one fraction, we multiply through by its LCM (3)

$3\timesx+3\times4y=3\times\dfrac{2}{3}x+3\times4$

$3x+12y=2x+12$

Putting all terms on the LHS (left hand side) and evaluating,

$12y+x-12=0$
