Will give brainliest. a student writes the equation for a line that has a slope of -6 and passes through the point (2, –8). y ) = -6(x - 2) y ) = -6x + 12 y ) + 8 = -6x + 12 + 8 y = -6x + 20 explain why the work is not correct.

They added 8 to each side,     --8 is +8    so we need to subtract - from each side not add 8 to each side

Step-by-step explanation:

We have a slope and a point

We can use point slope form

y-y1 = m(x-x1)

y--8 = -6(x-2)    

y+8 = -6(x-2)

Distribute the -6

y+8 = -6x+12

Subtract 8 from each side

      ERROR in the students work

They added 8 to each side,     --8 is +8    so we need to subtract - from each side not add 8 to each side

y+8-8 = -6x+12-8

y = -6x+4

The student should have simplified the equation to have y + 8 on the left.

Then, the student should have subtracted 8 from both sides of the equation.

The value of b should be 4, not 20.

Step-by-step explanation:

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8

hope this
