Which is an equivalent equation solved for the slope, m? m = yx + b m = m equals StartFraction y minus b Over x EndFraction. m = m equals StartFraction y Over x EndFraction minus b. – b m = y – m equals y minus StartFraction b Over x EndFraction.

m equals StartFraction y minus b Over x EndFraction

Step-by-step explanation:

The standard equation of a line is expressed as;

y = MX+b where;

m is the slope

cmb is the intercept

We are to get the equivalent expression for finding the slope.

Make m the subject of the formula to get this as shown;

From the equation;

y =MX+b

Subtract c from both sides;

y-b = MX+b-b

MX = y-b

Divide through by x;

mx/x = (y-b)/x

m = (y-b)/x

Heme the required expression is m = (y-b)/x OR m equals StartFraction y minus b Over x EndFraction

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
