VLD [36.1K]

Answer:

y = 5/4x - 18

Step-by-step explanation:

The slope, intercept form of a straight line is;

y = bx + c

Where, y = slope, given as 5/4

(x, y) is given as ; (8, - 8)

Hence, we need to obtain the value of c, which is the intercept.

x = 8 ; y = - 8

-8 = 5/4x + c

-8 = 5/4(8) + c

-8 = 10 + c

-8 - 10 = c

-18 = c

Hence, equation becomes ;

y = 5/4x - 18

841 jumping jacks per 4 minutes

\frac{841~jumping~jacks}{4~minutes}
