Work out the gradient of the line joining the points (2, 3) and (5,7)
Debora [2.8K]

Answer:

The gradient of the line joining the points P(x,y) = (2,3) and Q(x,y) = (5,7) is \frac{4}{3}.

Step-by-step explanation:

The gradient of the line joining two distinct point on a plane is represented by the slope of a secant line (m_{PQ}), that is:

m_{PQ} = \frac{y_{Q}-y_{P}}{x_{Q}-x_{P}} (1)

If we know that P(x,y) = (2,3) and Q(x,y) = (5,7), then the gradient of the line is:

m_{PQ} = \frac{7-3}{5-2}

m_{PQ} = \frac{4}{3}

The gradient of the line joining the points P(x,y) = (2,3) and Q(x,y) = (5,7) is \frac{4}{3}.

Find the x intercepts of y=2x^2+x-21
Anton [14]
The x intercept is when y=0. Substitute: 

2x^2+x-21=0

Solve for x by factoring.

2x^2-6x+7x-21=0

=2x(x-3)+7(x-3)=0

=(x-3)(2x+7)=0 

x=3 AND x=-\frac{7}{2} 

So therefore, we have our intercepts: 

(3,0) & (-7/2,0) 

Hope that helped!
