The points of the linear function on the graph would be (-2,0), (0,-6), (-3,3) and (1,-9). The slope intercept form is y=-3x-6. And the zero of the function is x=-2.
To find the graph, use the slope intercept equation and the points. The roots or “Zeros” are the x values where the graph intersects the x-axis. To find the roots (zeros), replace y with 0 and solve for X.
We use unitary method over here. To find out the number pages he writes in 1 hour we should; 16÷8 = 2. So Brennan writes 2 pages in 1 hour. Hence, in 10 hours he writes; 2 × 10 = 20. ∴ in ten hours Brennan writes 20 pages.
