Question

Write the equation for a line containing the point (0,2) and a slope of -7 (y=mx+b)

Answer 1

Answer:

$y=-\frac{7}{1}x+2$

Step-by-step explanation:

The slope of -7=

$-\frac{7}{1}$

so fractional slope is

$y=mx+b$

Substituting slope into a fraction,

$y=-\frac{7}{1} x+b$

Point is 0,2 so substitute in x and y.

$2=-\frac{7}{1} (0)+b$

Solve the equation.

$b=2$

So the equation for the line is

$y=-\frac{7}{1}x+2$

Hope this helps :D

Answer 2

Y = -7x + b
2 = 0 + b, b = 2
Y = -7x + 2
