Intro. to Equation of a Straight Line

 $y=mx+c$  is the general form of the equation of a straight line. What does the 'c' represent?

• the gradient of the straight line
  

• the independent variable
  

• the intercept of the line on the y-axis
  

• the dependent variable

 $y=2x-5$  is the equation of the straight line XY. This line cuts the y-axis at the point:

• (2, -5)
  

• (0, -5)
  

• (-5, 0)
  

• (-5, 2)
  

 $y=2x-5$  is the equation of the straight line XY. The gradient of line XY is:

• -5

•  $\frac{-5}{\ \ 2}$  

•  $\frac{\ \ \ 2}{-5}$  

• 2
