Answer:
Explanation:
(a. The independent variable is 40x. Independent variable: Not influenced by the changing of other factors, can be denoted by x
(b. The dependent variable is 70; it has no x values with it.
(C. the y intercept is 70, because again, it has no x besides it , and also, with the formula y=mx+b, b has to just be a number.
(d. The slope is 40 because its placed where the "m" is in the formula.
y=mx+b
y= SLOPEx+ y intercept
slope times x plus the y intercept
m= slope
b= y intercept
Hope this helps :)) Brainliest would be appreciated as i put some effort into this thanks :D
