Straight Line Graphs - GCSE Maths - Steps, Examples & Worksheet
WebIf the line goes straight up, then the line's equation is in the form x = ? because only the y value changes, the x value never changes. The x intercept is all you need to calculate for the equation because that x value is the same x value for every point on the line. So if your x intercept is (5,0) then your line's equation would be x = 5. WebY-Intercept of a Straight Line Where a line crosses the y-axis of a graph Just find the value of y when x equals 0 Example: In the above diagram the line crosses the y axis at y = 1 Example: Here the line crosses the y axis at y = −2 Point The y-intercept is an (x,y) point with x=0, so we show it like this (try dragging the points): how many energy levels does beryllium have

WebNov 1, 2012 · The equation of a straight line is usually taught in the form: y = mx + c which succinctly expresses the fact that if we plot y against x and the variables obey a relationship of this form we will obtain a straight line graph with gradient or slope m and intercept (where the line crosses the y-axis) c ( fig 1 ) WebNon-linear graphs can refer to any other equations that can be graphed on a coordinate plane that are not in linear form: y=mx+b. Normally, this means that it will be a large polynomial equation. With differently sized exponents per term, the graph can be manipulated into fantastic shapes and curves that are definitely not linear. WebDraw a straight line through the points. Check by graphing a third ordered pair that is a solution of the equation and verify that it lies on the line. Example 1 Graph the equation y = 2x - 6. Solution We first select any two values of x to find the associated values of y. We will use 1 and 4 for x. If x = 1, y = 2 (1) - 6 = -4 high tsh on thyroxine
