Write the equation of line that passes through (-1,3) and (-5,-3)
Black_prince [1.1K]

Answer:

y =  \frac{3}{2} x + 4 \frac{1}{2}

Step-by-step explanation:

y=mx+c

where m is the gradient and c is the y-intercept of the line

Let's find the gradient of the line first.

gradient =  \frac{y1 - y2}{x1 - x2}

Using the above formula,

gradient \: of \: line \\  =  \frac{3 - ( - 3)}{ - 1 - ( - 5)}  \\  =  \frac{3 + 3}{5 - 1}  \\  =  \frac{6}{4}  \\  =  \frac{3}{2}

Subst. the gradient into m:

y =  \frac{3}{2} x + c

Now, find the value of c by substituting a coordinate into the above equation.

when x=-1, y=3,

3 =  \frac{3}{2} ( - 1) + c \\ 3 =  -\frac{3}{2}  + c \\ c = 3 +  \frac{3}{2}  \\ c = 4 \frac{1}{2}

Therefore the equation of the line is

y =  \frac{3}{2} x +  4\frac{1}{2}

A band expects to put 12 songs on their next CD. The band writes and records 25​% more songs than they expect to put on the CD.
sweet-ann [11.9K]
12 songs. 25% of 12 is 3, so you add 3 to 12 and get 15. You then find that 20% of 15 is 3 so you subtract 3 from 15 and get 12 again.
