Question

Create an equation in slope-intercept form from A line that includes the point (6,–7) and has a slope of 2.

Answer 1

Use the equation y=mx+c

the slope(m) is 2,y is -7and x is 6

therefore you firstly have to find the y intercept (c)

y=mx+c

-7=2(6)+c

-7=12+c

-7-12=c

-19=c

then replace the gradient and y intercept in the equation

y=mx+c

y=2x-19

or you can use the formula y-y1= m( x-x1)

I hope this helps
