To find the gradient of the straight line that passes through the point (-3, 6) and the midpoint of the points (4, -5) and (-2, 9), we can follow these steps: Step 1: Identify the PointsLet point A be (-3, 6), point B be (4, -5), and point C be (-2, 9). Step...
the graph of alinear function 是一条直线line,这条直线的函数表达式也称作直线方程Equations of a straight line,斜截式gradient-intercept form是y=ka+b,其中常数k称为这条直线的斜率gradient,b称为这条直线的y截距y-intercept。 我们需要知道的是: x截距x-intercept是方程中y=0时得到的x值,也叫做函数的零点...

(a) The gradient of the line through R and Q is 0.5Show how you can work this out from the graph.___(b) What is the equation of the straight line through R and Q?(c) Write the equation of a line that is parallel to the straight linethrough R and ...
Write the gradient of the line perpendicular to the line with gradient. (a) 5 (b) 7 (c) -4 (d) -9 Gradient: In mathematics, the gradient is also referred to as the slope. It defines the direction and steepness of a line. The gradient of a line ca...
To calculate the gradient of a straight line we choose two points on the line itself.The difference in height (y co-ordinates) ÷ The difference in width (x co-ordinates). If the answer is a positive value then the line is uphill in direction. ...
