What is the equation of the line that passes through (4,3) and (2, -1)? y = 6x+4
y = 1/2 x -2
y = 2x-5
y = 4x -13

c

you need to find the slope and then y intercept

m=y2-y1/x2-x1

so m=2

now y intercept

3=2(4)+b

solve for b

u get -5

therefore

y=2x-5

The expression that expresses 12 + 42 by using the GCF is 6(2 + 7). The correct option is the third option 6(2 + 7)

To determine which of the given options expresses the given expression (12 + 42) by using the GCF (Greatest common factor),

First, we will list the factors of the numbers in the given expression

The numbers are 12 and 42

1, 2, 3, 4, 6 and 12

1, 2, 3, 6, 7, 14, 21 and 42

From above, we can observe that the greatest common factor of 12 and 42 is 6.

Now, we will factorize the given expression, using the greatest common factor (GCF)

The expression is 12 + 42

Factorizing

12 + 42 = 6(2 + 7)

Hence, the expression that expresses 12 + 42 by using the GCF is 6(2 + 7). The correct option is the third option 6(2 + 7)
