Step 1: Find the value of one variable in terms of the other.

Step 2: Substitute the value you just found for this variable in the other equation.

Step 3: Use your new value for the second variable to find the first.

Now that we know the values for a and b we can find the value of 4a+b.
Answer:
y = 3x + 9
Step-by-step explanation:
y = 3x + 6
Parallel slope = 3
(-2, 3)
Slope-intercept:
y - y1 = m(x - x1)
y - 3 = 3(x + 2)
y - 3 = 3x + 6
y = 3x + 9
As per this theorem the two triangles are congruent if two angles and a side not between these two angles of one triangle are congruent to two corresponding angles and the corresponding side not between the angles of the other triangle.
