Answer:
3. is D and 4. is B
Step-by-step explanation:
Slope intercept form is y=m(x)+b
M is our slope, which we find using the formula y2-y1 and x2-x1. B is the Y intercept where the line intercepts the Y axis.
Hello! We already have the equation set up, which is 9x = x + 4. Let's solve for x. Subtract x from both sides to get each side by itself x - x cancels out. 9x - x is 8x. That leaves 8x = 4. Now, divide each side by 8 to isolate the x. 8x/8 cancels out. 4/8 is 4/8 or 1/2 in cimplest form. Let's plug this value in and see if it works. 9 * 1/2 is 4 1/2. 1/2 + 4 is 4 1/2. 4 1/2 = 4 1/2. There. x = 1/2.
