What is the equation in point-slope form of the line that passes through the point (-1, -4) And has a slope of -3?
Reptile [31]
Point-slope form is y- y_{1} =m(x- x_{1} ) where y1 and x1 are your points from the coordinate and m is the slope.  So yours would look like this: y-(-4)=-3(x-(-1)) or y + 4 = -3(x + 1)

Please help me ?????????
scZoUnD [109]

Answer:

Because 4 is a perfect square

Step-by-step explanation:

When simplifying a radical, you have to look for perfect squares. 4 is a perfect square but x is not. Variables are only perfect squares if they have even numbered exponents so the x has to stay in the radical.

What is the equation of the line passing through the points (2, -1) and (5.-10) in slope-intercept form
vagabundo [1.1K]

Answer:

y = -3x + 5

Step-by-step explanation:

Usually by drawing a simple graph, you can tell what the equation is, even if the graph isn't 100% accurate. From the points alone, you can tell that the slope is negative, since as you increase in x you decrease in y (which is a negative relationship). You can tell that it's +5 rather than -5 because the graph sketched shows that the line goes above 0 (indicating a positive number), rather than below (a negative number).
