What is 1/3 of 21? Correct Answer slople is -3 and y-intercept is 5 Explanation The equation -15= -3y - 9x can be rearranged to y = -3x - 5. By comparing this equation to the standard form y = mx + b, we can determine that the slope is -3 and the y-intercept is -5....
First of all, let's rearrange the equation into a slope-intercept form: $$y = -3x + 7 $$ Using the definition, a parallel line to the given line... Learn more about this topic: Slope-Intercept Definition, Formula & Graphs from ...
What would be the slope and the y - intercept for the line represented by the equation y = 4 x - 7? What are the coordinates of the points at which the slope of a function with the equation y=x^4-8x^2 is equal to zero? What is the equation of the line that has a slope of ...
In calculus, the slope of a line, also known as the gradient is important to calculate because it explains how steep the line is. If we have an equation of a line in the formy=mx+c, the slope of this line is calculated asΔyΔx=m. ...

We know m, and also know that (x1, y1) = (3, 2), and so we have: y − 2 = 3(x − 3) That is a perfectly good answer, but we can simplify it a little: y − 2 = 3x − 9 y = 3x − 9 + 2 y = 3x − 7Example...
