Answer:
The first step to solving the equation is:
Hence, 3x + 24 = 42 is the correct option.
Step-by-step explanation:
Given the equation
First of all, we need to apply the distributive law on the left side of the equation to expand the equation.
So the equation would be expaneded using the distributive law on the left side of the equation
∵ a(b+c) = ab + ac
Therefore, the first step to solving the equation is:
Hence, 3x + 24 = 42 is the correct option.

Answer:
y = -2x + 2
Step-by-step explanation:
Given the following data;
Points on the x-axis (x1, x2) = (2, -1)
Points on the y-axis (y1, y2) = (-2, 4)
To find the equation of line in slope intercept form;
First of all, we would determine the slope of the line.
Mathematically, slope is given by the formula;
Substituting into the equation, we have;
Slope, m = -2
Next, we would use the following formula to find the equation of the line;
y - y1 = m(x - x1)
Substituting into the formula, we have;
y - (-2) = -2(x - 2)
y + 2 = -2x + 4
y = -2x + 4 - 2
y = -2x + 2 = mx + c
