Answer:
a) the gradient of the linear graph is: ![\mathbf{\frac{-1}{3} }](https://tex.z-dn.net/?f=%5Cmathbf%7B%5Cfrac%7B-1%7D%7B3%7D%20%7D)
b) the y-intercept of linear graph is -1
Step-by-step explanation:
a) Find the gradient of the linear graph.
The formula used to find gradient is same as slope
![Gradient=\frac{Change \ in \ y \ coordinate}{Change \ in \ x \ coordinate}\\or\\Gradient=\frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=Gradient%3D%5Cfrac%7BChange%20%5C%20in%20%5C%20y%20%5C%20coordinate%7D%7BChange%20%5C%20in%20%5C%20x%20%5C%20coordinate%7D%5C%5Cor%5C%5CGradient%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
Take any 2 points from the graph.
I will take: (-3,0) and (0,-1)
Putting values in formula and finding gradient
![Gradient=\frac{y_2-y_1}{x_2-x_1} \\Gradient=\frac{-1-0}{0-(-3)} \\Gradient=\frac{-1}{3}](https://tex.z-dn.net/?f=Gradient%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D%20%20%5C%5CGradient%3D%5Cfrac%7B-1-0%7D%7B0-%28-3%29%7D%20%5C%5CGradient%3D%5Cfrac%7B-1%7D%7B3%7D)
So, the gradient of the linear graph is: ![\mathbf{\frac{-1}{3} }](https://tex.z-dn.net/?f=%5Cmathbf%7B%5Cfrac%7B-1%7D%7B3%7D%20%7D)
b) Find the y-intercept of linear graph
The y-intercept of linear graph is the value of y at the point where the line crosses the y axis.
So, in the given graph, that point is -1
So, the y-intercept of linear graph is -1
