Given:

The objective is to find the slope of the straight line.

Explanation:

The general equation to find the slope is,

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

Let's consider two coordinates from the graph.

\begin{gathered} (x_1,y_1)=(0,0) \\ (x_2,y_2)=(-1,5) \end{gathered}

On plugging the values in the equation of slope,

\begin{gathered} m=\frac{5-0}{-1-0} \\ m=-5 \end{gathered}

Hence, the slope of the straight line is -5.

Find the equation of a line parallel to −5x+y=2 that contains the point (5,−2). Write the equation in slope-intercept form.
mario62 [17]

Answer:

L2: y-0 = 5/2(x-5)

y = 5/2x-25/2

Step-by-step explanation:

Parallel lines have same slopes.

Line 1,   L1:  5x-2y=20   is in standard form Ax+By=C therefore slope m1= -A/B = -5/-2 = 5/2 or you can solve it for y so you will have the equation in slope-intercept form.

5x-2y = 20

-2y = -5x+20

y = (-5/-2)x+20/(-2)

y = (5/2)x-10 hence m1=5/2 and y-intercept is -10

Line 2 , L2:   y-y1 = m (x-x1),  m=m2=m1=5/2

Point p(5,0) or p(x1,y1) therefore x1=5 , y1=0 and m=5/2

L2: y-0 = 5/2(x-5)

y = 5/2x-25/2

Area of rectangle = l × b

l = 70cm

b = 8cm

Area = 70 × 8 = 560cm²

Area of rectangle = l × b

l = 78cm

b = 15cm

Area = 78 × 75 = 1170cm²
