Write the equation of the line in fully simplified slope-intercept form

y = m(x-2) + 1

Step-by-step explanation:

y' = 1, x' = 2(From the graph.

...equation of a straight line is y - y' = m(x - x') where m represent the gradient of the slope.

substitute the values of x' and y' into the line equation.

therefore we have, y-1 = m(x - 2)

Now let's solve for y.

y = m(x-2) + 1

that's it.

i think the answer is b

$320 to $405

step by step explanation:

in one day he earns between $64 and $81

therefore if he works for 5 days, he will earn between 64 x 5 to 81 x 5

= $320 to $405
