1. Since we have a slope, and only one point we can use point slope form. Point slope form is y - y1 = m(x-x1). We will replace the y1 and x1 with our coordinates. Additionally, we will replace m with -2. y - 4 = -2(x-3). If you wish to solve this, we need to first distribute. y - 4 = -2x+ 6. Then, we can add 4 which will give us 10. y = -2x + 10. 2. We just need to find the slope here. To find the slope, you can use the formula y2 - y1 / x2 - x1. 3 - (-1) / 9 - 1 gives us 4/8 or 1/2. Plot the points you’re given, and then use the slope to plot more points so you can create your line.
