Determine the slope and y-intercept of the line 

Step 1: Solve for yyyStart with the given equation:10x−2y=510x - 2y = 5Isolate yy by moving 10x10x10x to the other side:−2y=−10x+5-2y = -10x + 5Now, divide everything by −2-2−2 to solve for yyy:y=5x−52​Step 2: Identify the slope and y-interceptNow that we have the equation in slope-intercept fo...

Calculate the slope of the line given the points (0, 0) and (5, 2).

To calculate the slope of the line between two points, use the slope formula:slope=y2−y1x2−x1\text{slope} = \frac{y_2 - y_1}{x_2 - x_1}​​Given the points (0,0)(0, 0)(0,0) and (5,2)(5, 2)(5,2), substitute the coordinates into the formula:slope=2−05−0=25\text{slope} = \frac{2 - 0}{5 - 0} = \frac{2}{5}...
