Explanation / Answer

a) To find the y intercept, put x = 0. We get y = -8, which is the y intercept.

The slope is the co-efficient of x which is 6.5.

If you want to graph the equation, use the points of the intercepts. We know that the y intercept is -8, therefore the line cuts the point at (0 ,-8).

Similarly we can find the x intercept, which is when y = 0, and we get 0 = 6.5x -8. Solving x = 8/6.5 = 1.23, therefore the 2nd point is (1.23,0).

The line formed by joining these 2 points is the line y = 6.5x - 8
