The equation of point-slope form can be converted to the equation of slope-intercept form using algebraic operations. Answer and Explanation:1 The slope of the line is,m=−14. (x1,y1)=(−2,9) The point-slope form of the line is: ...
Since we want to find the slope of the line that is parallel to 2x - 4y - 22 = 0, and parallel lines have the same slope, we simply need to find the...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our experts...
Picking x = −1, I get: y = −2(−1) + 3 = 2 + 3 = 5 Picking x = 2, I get: y = −2(2) + 3 = −4 + 3 = −1 Then the points (−1, 5) and (2, −1) are on the line y = −2x + 3. The slope of the line is then calculated as:...

问题：tx+12y=-3，t是常数，如果这个线性函数的斜率是-10，t是几？解答：原式可化为(-t/12)x-1/4=y 斜率为-t/12，因为斜率为-10 所以可得-t/12=-10 解得t=120 tx
Slope of Line:The slope of any line that passes through any two points can be easily calculated by dividing the change in y between two points by the change in x between those two points. In mathematical form, if {eq}(x_1,y_1) {/eq} and {eq}(x_2,y_2) {/eq}...
