User: Indicate in standard form the equation of the line passing through the given points. B(0, 0), C(4, -4)

Weegy: The equation of the line through the given points P(0, -4), Q(5, 1) in standard form is x - y = 4.

User: Indicate in standard form the equation of the line passing through the given points. P(6, 2), Q(8, -4)

Weegy: (6,2)-(8,-4) Use y=mx+b to calculate the equation of the line, where m represents the slope and b represents the y-intercept. To calculate the equation of the line, use the y=mx+b format. Slope is equal to the change in y over the change in x, [ or 'rise over run'. m=(change in y)/(change in x) The change in x is equal to the difference in x-coordinates (also called run), and the change in y is equal to the difference in y-coordinates (also called rise). m=(y2-y1)/(x2-x1) Substitute in the values of x and y into the equation to find the slope. m=(-4-(2))/(8-(6)) Multiply -1 by each term inside the parentheses. m=(-4-(2))/(8-6) Subtract 6 from 8 to get 2. m=(-4-(2))/(2) Multiply -1 by each term inside the parentheses. m=(-4-2)/(2) Subtract 2 from -4 to get -6. m=(-6)/(2) Reduce the expression (6)/(2) by removing a factor of 2 from the numerator and denominator. m=-(3) Multiply -1 by each term inside the parentheses. m=-3 Find the value of b using the formula for the equation of a line. y=mx+b Substitute the value of m into the equation. y=(-3)*x+b Substitute the value of x into the equation. y=(-3)*(6)+b Substitute the value of y into the equation. (2)=(-3)*(6)+b Since b is on the right-hand side of the equation, switch the sides so it is on the left-hand side of the equation. (-3)*(6)+b=(2) Multiply (-3) by (6) to get (-3)(6). (-3)(6)+b=(2) Remove the parentheses around the expression 2. (-3)(6)+b=2 Multiply -3 by 6 to get -18. (-18)+b=2 Reorder the polynomial -18+b alphabetically from left to right, starting with the highest order term. b-18=2 Find the value of b. b=20 Now that the values of m(slope) and b(y-intercept) are known, substitute them into y=mx+b to find the equation of the line. y=-3x+20 Ax + By = C 3x +y= 20 is standard form of the equation of the line. ]
