Step-by-step explanation:

This question is incomplete, as the required scatter plot is not included in the question. I will answer your question with the attached plot.

Solving (a): The equation

Pick any  on the line

Calculate the slope (m)

The equation is then calculated as:

This gives:

Solving (b): y, when

Substitute

Solving (c): x when

Substitute

Collect like terms

Solve for x

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3

35x 3= 105

step-by-step explanation:
