7to the 3rd power times 7 to the negative 5th power

The answer 0.02040816326.

7^3 * 7^-5  = 7^(3+ -5)  = 7^-2

7^-2 can be written as 1/7^2  or 1/49.

Abit confused about what you mean, but i think you might be referring to slope intercept form: y = mx + bin that case b, or the y intercept is already given.(0,-1)find the slope by using the formulay2 - y1/x2 - x1the final slope will be 4/2, equivalent to 2.now your equation should look like thisy = 4/2x -1sorry if this didn’t you out!
