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 ...
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...
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...
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...
Answer to: The slope of the line containing points Y and Z is ___. a. -0.5 b. -1 c. -2 d. -4 By signing up, you'll get thousands of step-by-step...
The case in which the number of equations coincides with the number of unknowns is encountered most frequently. One linear equation in one unknown has the form ax = b. When a ≠ 0, the number b/a will be its solution. A system of two linear equations in two unknowns has the form ...
If the slope of one of the lines represented byax2+6xy+y2=0is twice the other, then a is equal to View Solution If the slope of one of the lines given byax2−6xy+y2=0is square of the other, then a = View Solution Free Ncert Solutions English Medium ...
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.
Earlier in this chapter we have expressed linear equations using the standard form Ax + By = C and also y= mx +b. Now we're going to focus on the slope-intercept form y = mx + b. In the slope-intercept form you use the slope of the line and the y-intercept to e...
