Find the equation of the line that passes through the points (1, 6) and (2, 8). By substitution in this equation, show that (3, 10) also lies on this line.

y = 2x + 4

Step-by-step explanation:

y2 - y1/ x2- x1  

= 8 - 6 / 2 - 1

= 2

So now our equation is y = 2x + b (from y = mx+b). Now plug in the coordinates to find the y-intercept.

y = 2x + b

8 = 2(2) + b

8 = 4 + b

4 = b

The y-intercept is 4.

If we put one of the values like the x in the equation, we should get the y value.

y = 2x + 4

y = 2 (3) + 4

y = 6 + 4

y = 10

(3,10)

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!

welll its a very hard question but ill

step-by-step explanation:

first you take the 6 dollars and add 10 to it then add the 50 to that then multiply by 8 with xy and your answer will be

hope this
