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...
Which expression represents the slope of a line? A. y = mx + b B. ax + by = c C. m = (y2 - y1)/(x2 - x1) D. x = h 相关知识点: 试题来源: 解析 C。选项 A 是直线方程的一般式,B 是二元一次方程,D 表示一条垂直于 y 轴的直线。选项 C 是斜率的计算公式。...
Slope is a measure of the rate of incline or steepness of a line on a graph. You can find the slope of a line by comparing any 2 points on the line. A point is an x and y value of a cartesian coordinate on a grid. Slope, expressed asm, is equal to the rise between two coord...
c) d) 4 −3 Horizontal and vertical linesWhat number is the slope of a horizontal line -- that is, a line parallel to the x-axis? And what is the slope of a vertical line?A horizontal line has slope 0, because even though the value of x changes, the value of y does not. ...
then the slope of the line ab is given as: \(\begin{array}{l} m = tan\ \theta =\frac{y_2~-~y_1}{x_2~-~x_1}\end{array} \) where θ is the angle which the line ab makes with the positive direction of the x-axis. θ lies between 0° and 180°. it must be ...
The slope of the line is 5 / 3.Convert from standard form to the slope-intercept form: the general formExample #3: Find the slope of Ax + By = C Ax + By = C Subtract Ax from each side of the equation. Ax - Ax + By = C - Ax ...

In the xy - plane, the line with equation ax + by + c = 0, where abc≠ 0, has slope . What is the value of b ? (1) a = 4 (2) c = −6 选项: 答案: A 经典答疑 发起提问 提问: 点此查看答疑 这个题abc不等于0只能说明任意一个数不为零,直线有斜率只能说明B不等于0,但是...
When a ≠ 0, the number b/a will be its solution. A system of two linear equations in two unknowns has the form (1) a11x1 + a12x2 = b1 a12x1 + a22x2 = b2 where a11, a12, a21, a22, b1, and b2 are given numbers. The solution of system (1) can be obtained by using ...
Answer to: Find the slope of line that is tangent to the given function's graph for the specified value of the independent variable. f(x) = 9x - 8;...
