A level line equation
WebThe equation y = mx + c is the general equation of any straight line where m is the gradient of the line (how steep the line is) and c is the y -intercept (the point in which the line crosses the y -axis). y = mx + c is a linear equation and the variables x and y relate to coordinates on the line. WebThe reliability level of Cronbach’s alpha of the multiple linear regression equations was moderate for the intensity of 50% (0.51); for the intensities of 60, 70 and 80%, it …

WebA straight line with a gradient of −2 passes through the point (4, −1). Find the equation of the line, and draw its graph. Solution As the graph is a straight line, its equation can be written in the form y =mx +c. As the gradient is −2, m in this equation must be −2, and y =−2x+c. The point (4, −1) lies on this line, so its x and y ... WebThe general equation of a straight line is y = mx+c, where m is the gradient, and y = c is the value where the line cuts the y-axis. This number c is called the intercepton the y-axis.

WebExample 3: Find the equation of the horizontal line passing through the point (4,7). Solution: The equation of the straight line in the slope-intercept form is y = mx + b. The slope of a horizontal line = 0. ⇒ m = 0. For a line passing through (4, 7) the equation is y = (0) x + b. The line cuts the y-axis at (0, 7). Thus the y-intercept is 7 ...
