For the straight line defined by the points (4, 53) and (6, 87), determine the slope and y-intercept. M= ? (slope) b= ? (y-intercept)
**
Equation for a straight line: y=mx+b, m=slope, b=y-intercept
slope of given line=∆y/∆x=change in y/change in x=rise/run=(87-53)/6-4=34/2=17
Equation: y=17x+b
solve for b using coordinates of one of given points (4,53)
63=17*4+b
b==-5
Equation: y=17x-5
..
slope,M =17
y-intercept=-5
