WebJun 6, 2016 · In a line graph, the information or data is represented as a series of markers, or dots, and is then connected to one another by a straight line. Usually, data that varies … WebJan 23, 2024 · y = 3*1. y = 3. So the point (x,y) = (1,3) is also on the line. You can repeat this process for any x value you want; however, we only need two points to form the line. Plot (0,0) and (1,3). Then draw a straight line through both points. Extend the line as far as you can in either direction. This forms the graph of y = 3x. WebMar 29, 2024 · y = − 2x +3 is in this form. ⇒ y-intercept = b = 3 → (0,3) is point on line. To find another point on the line, choose any value for x, substitute into the equation and evaluate for y. x = 3 → y = ( −2 × 3) +3 = − 6 + 3 = − 3. ⇒ (3, − 3) is a point on the line. Plot the 2 points, draw a straight line through them to obtain ... simptech solutions
