It should be noted that there are only two unknowns in theequation of a straight linebecause the equation of every straight line can be put in the form ax + by + c = 0, where a and b are two unknowns. It is important to note here that x and y are not unknowns. In fact, th...
Slope of a is the change in y coordinate with respect to the change in x coordinate. Visit BYJU'S to learn the slope formulas, equations and many solved examples in detail.
Write the equation of the parabola x=-y^2 + 2y - 6 in standard form. What is a linear equation? How do we determine the x and y intercepts from the equation of a polynomial? In the standard form of a line, Ax + By = C, what do A, B, and C stand for?
$$m= \dfrac{-A}{B} $$ Where {eq}m {/eq} is the slope. Answer and Explanation:1 Given: $$2x - 4y = 10 $$ First, the general equation of the line has the form {eq}Ax+By = C {/eq}. We must identify the variables of the given... ...
Divide each side of the equation by B so the equation can be written in slope-intercept form. By / B = (-Ax + C) / B y = -Ax / B + C / B y = (-A / B)x + C / B The slope of the line is -A / B.How to write the equation of a line in point-slope formEmail...
