The slope of a line is 5- and the point (9,8) is on the line. express the line in slope-intercept form

Point slope form is the line through (a,b) with slope m is

y - b = m(x - a)

y - 8 = 5(x - 9)

y - 8 = 5x - 45

y = 5x - 37

y = 5x - 37

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2
