Write the slope-intercept equation for the line that passes through (-4,-3)and (-6,7)
Equation of a straight line: y=mx+b, m=slope, b=y-intercept
For given equation:
Slope,m=∆y/∆x(7-(-3))/(-6)-(-4))=(7+3)/-6+4)=10/-2=-5
equation: y=-5x+b
solve for b using coordinates of any one of given points like (-4,-3)
-3=-5*-4+b
b=-23
equation: y=-5x-23
