Find the distance between points P(3, 4) and Q(4, -6) If necessary round to the nearest hundredth.

Andrei [34K]

Answer:

10.05 units

Step-by-step explanation:

We can find the distance between these points using the distance formula. The distance formula is:

$\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

We know that x1 is 3, x2 is 4, y1 is 4, and y2 is -6, so we can substitute inside the equation.

$\sqrt{(4 - 3)^2 + (-6 - 4)^2} \\\\\sqrt{1^2 + -10^2} \\\\\sqrt{1 + 100} \\\\\sqrt{101} \\\\\approx10.05$

Hope this helped!

Find the slope-intercept form of the line whose slope is 5 and that passes through the point left (-2,8)

Doss [256]

$\text{The slope-intercept form:}\ y=mx+b\\\\\text{m-a slope; b-a y-intercept}$

$\text{We have:}\\m=5\\\text{therefore}\ y=5x+b$

$\text{We know, the line passes through the point}\ (-2;\ 8)\to x=-2;\ y=8\\\\\text{substitute the values of x and y to the equation of the line:}\\\\8=5(-2)+b\\\\8=-10+b\ \ \ |+10\\\\b=18$

$\text{Your answer:}\ y=5x+18$
