Answer:

a = -2

Step-by-step explanation:

Subtract 10 from both sides:

7a + 10 - 10 = 2a - 10

Simplify:

7a = 2a - 10

Subtract 2a from both sides:

7a - 2a = 2a - 10 - 2a

Simplify:

5a = -10

Divide both sides by 5 and simplify:

a = -2

Answer:

A = -2

Step-by-step explanation:

Subtract 10 from both sides:

7a + 10 = 2a -10

Simplify the expression, 7a = 2a - 10

Subtract 2a from both sides next

7a - 2a = 2a - 10 - 2a

Subtract 7a - 2a

5a = -10

5a / 5 = -10/5

a = -2

Which equation represents the line that passes through points B and C on the graph? 2 4 3 B 3 4 5 ภา
777dan777 [17]

The point B has coordinates (-4,2) and C has coordinates (-2,-2). We are going to calculate the slope of the line

m=\frac{y2-y1}{x2-x1}=\frac{-2-2}{-2-(-4)}=-2

Then, we are going to calculate the intercept using the slope m=-2 and the point (-4,2).

y=mx+b

2 = -2*(-4)+b

Isolating b we get

2-8=b= -6

The equation would be

y=-2x-6, option A
