Answer:
- 5
Step-by-step explanation:
The opposite of 7c is - 7c, thus the sum is
7c - 5 + (- 7c)
= 7c - 5 - 7c ← collect like terms
= - 5
To find the slope, you should rearrange the equation into slope-intercept form, ie. y = mx + c, where m is the gradient.
y - 9 = 15(x - 5)
y = 15(x - 5) + 9 (Add 9 to each side)
y = 15x - 15*5 + 9 (Expand 15(x - 5))
y = 15x - 75 + 9
y = 15x - 66
Therefor, the slope of the equation is 15.
