Find the equation of the line that passes through the points (-3,0) and (4,2). Using point slope formula
astra-53 [7]

Answer:

\large\boxed{y-0=\dfrac{2}{7}(x+3)}\\\downarrow\\\boxed{y=\dfrac{2}{7}x+\dfrac{6}{7}}

Step-by-step explanation:

The point-slope form of an equation of a line:

y-y_1=m(x-x_1)

<em>m</em><em> - slopei</em>

The formula of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

======================================

We have the points (-3, 0) and (4, 2).

Substitute:

m=\dfrac{2-0}{4-(-3)}=\dfrac{2}{7}

Put the value of the slope and the coordinates of the point (-3, 0) to the equation:

y-0=\dfrac{2}{7}(x-(-3))

y-0=\dfrac{2}{7}(x+3)

Converto to the slope-intercept form (<em>y = mx + b</em>):

y=\dfrac{2}{7}x+\dfrac{6}{7}

△ABC is similar to △DEF .<br><br> AB=5 inches, BC=9 inches, and DE=7.5 inches.<br><br> What is EF ?
Vikki [24]
Similar triangles have corresponding sides with proportional lengths.

AB/BC = DE/EF

5/9 = 7.5/EF

5(EF) = 9 * 7.5

5(EF) = 67.5

EF = 13.5
