x-intercept is at y=0y=x^2+6x+80=x^2+6x+80=(x+4)(x+2)x=-4,-2x-intercepts are at (4,0) and (-2,0)
x=1
y = 5x + 6At the x-intercept, y = 0 .5x + 6 = 05x = -6x = -6/5
(X + 5)(X + 1) FOIL this. X2 + 1X + 5X + 5 Gather terms. X2 + 6X + 5 ----------------------------those were the factors
3x + 5 = 6x + 23 -3x = 18 x = -6

x-int. is -5 y-int. is 6
x=1
The x-intercept is where y = 0 → 6x + 5(0) - 3 = 0 → 6x = 3 → x = 0.5 The y-intercept is where x = 0: → 6(0) + 5y - 3 = 0 → 5y = 3 → y = 0.6
y = 5x + 6At the x-intercept, y = 0 .5x + 6 = 05x = -6x = -6/5
x squared +6x +5 is a quadratic expression that can be factored as (x+1)(x+5)
2y = -6x + 8 The y intercept occurs when x = 0 2y = 8 therefore y = 4
x2 + 6x + 5 can be factored into (x+1) (x+5)
-6x + 94(5 - x) = -6x + (94 × 5) + (94 × -x) = -6x + 470 - 94x = 470 - 100x
6X + 5Y = 8 subtract 6X from both sides 5Y = -6X + 8 divide both sides by 5 Y = -6/5X+ 8/5 now you have a line of slope -6/5 that intersects the Y axis at 8/5. (Solve for X to get X intercept)
x-intercept happens when y=0 0=x2+6x-7 0=(x - 1)(x + 7) x-intercepts are x=1 and -7
