Q. What is the slope of the line?−4x+7=2y−3Choose 1 answer:(A) −21(B) −31(C) −3(D) −2
Rearrange equation: Rearrange the equation to solve for y, making it easier to identify the slope. Start by adding 4x to both sides to isolate terms involving y on one side. −4x+7+4x=2y−3+4x7=2y−3+4x
Simplify and isolate: Next, simplify and isolate 2y by moving the constant term to the other side. Add 3 to both sides.7+3=2y+4x10=2y+4x
Subtract to isolate: Now, subtract 4x from both sides to fully isolate the 2y term.10−4x=2y
Divide to solve: Divide every term by 2 to solve for y.(10−4x)/2=y5−2x=y
Identify slope: From the equation y=5−2x, identify the coefficient of x, which represents the slope of the line.Slope = −2
