Find the equation of the line through point (2,−1) and parallel to 2x+5y=15. Use a forward slash (i.e. "/") for fractions (e.g. 1/2 for 1/2 ).

Question

please help

Answer 1

The easiest way to find the equation is to evaluate the expression 2x + 5y for x = 2 and y = -1

2x + 5y = 2*2 +5*(-1) = 4 - 5 = -1

Hence the equation will be 2x +5y = -1

We can also convert it to the slope-intercept form, obtaining y = - (2/5) x - (1/5)
