Y=2x+6
gradient is found from the formula,

y intercept is found by subbing the values of (-1,4) into the equation y=2x+c
The number of zeros in the product has 5 zeros and the zeros in the factor has 4 zeros because when you multiply 5,00x by8 you get 40,000
Answer:
-15/4
Step-by-step explanation:
slope = change in y / change in x = (-7 - 8) / (7 - 3) = -15/4
I haven't got a calculator right now but substitute the values into the cosine law so:
8² = 5² + c² - (2 x 5 x c x cos58)
and then use sine law to find B
sin58/8 = sinB/5
If you put in a calculator 11^2+9^2 then square root that it should give you your answer
