Question

write an equation that would define the same line as 7x-2y=5

Answer 1

$7x-2y=5$ Original Equation
$-2y=-7x+5$ Subtract 7x from both sides
$y=3.5x-2.5$ Divide by -2 on both sides. MAKE SURE YOU DO IT TO BOTH NUMBERS AND REMEMBER SIGNS :)
This final form is known as slope-intercept form, y=mx+b. The x and y are point values, the m is slope, and b is the y intercept. Another form of the answer with fractions is
$y= \frac{7}{2}x - \frac{5}{2}$
