Nikki gathered data about the length of time she spent listening to the radio and the number of commercials she heard. she organized the data
in a scatter plot, where x represents the minutes spent listening and y represents the number of commercials. then she used the graphing tool
to find the equation of the line of best fit:
y=0.338x - 1.387.
based on the line of best fit, for approximately how many minutes will nikki need to listen to the radio to hear 20 commercials?

answer: 590

step-by-step explanation:

it should be a.

hope it

answer:

given the linear inequality :

add 2y to both sides we get;

simplify:

add 12 to both sides of an equation;

simplify:

divide both sides by 2 we get;

or

the related equation for the inequality equation [1] is;

y-intercepts defined as the graph crosses the y-axis.

substitute x =0 in [2] to solve for y;

y = 6

x-intercepts defined as the graph crosses the x-axis.

substitute value y = 0 to solve for x;

subtract 6 from both sides we get

multiply both sides by 2 we get;

or

x = -12

now, plot these point (0, 6) and (-12, 0) on graph as shown below and shade the graph below the solid line.
