Ok, so rembmer some basica exponential rules and some fraction rules
(ab)/(cd)=(a/c)(b/d)
and

so

y=-3x+30
Step-by-step explanation:
Answer/Step-by-step explanation:
Given:
Line equation => 
Required:
x-intercept and y-intercept of the line.
SOLUTION:
The x-intercept is the point where the line intercepts the x-axis. To find the x-intercept of the line for which the equation is given above, set y = 0 and solve for x.






(approximated)
The y-intercept is the point where the line intercepts the y-axis. At this point, x = 0. Set x = 0 and solve for y to find the y intercept.
