Question

i really need to know the equation of the line that is shown on the graph in slope intercept form (y=mx+b). questions 4-9. it’s due at 11:59 please i need it

Answer 1

Here's how to solve each problem. To find the slope, you use the formula rise/run. Look at the 2 bolded points on the graph. Find the rise/run of those points. That is the slope. The y-intercept is the point where the y-value is directly on the y-axis. This point is already given in each of the graphs. let's work out the first graph (Number 4)

Explanation:

First, calculate the run from the point on the y-axis. Move the desired amount of spaces to the left, until you reach the point directly under the point in the 2nd quadrant. The run is -6. Next, rise up the desired amount of spaces to the point that were under. The rise is 3. Remember the formula: rise/run. Divide the rise by the run to get the slope: -0.5 or -1/2. The y-intercept is on the y-axis; it is given for each of the graphs. In this situation, the y-intercept is 3. So, here's how your equation should look:

y = mx + b (y = -0.5x + 3)

Repeat this for each graph, good luck :)

Answer 2

Explanation:

4. y=-6/3x+3 (if you can simplify put y=-2x+3)

5. y=5/2x+1

6. y=-8/2x -5 (if you can simplify put y=-4x-5)

7. y=-6/6x+2 (if you can simplify put y=-x+2)

8. y=4/6x-4 (if you can simplify put y=2/3x-4)

9. y=6/5x+0

hope this helped!!!
