9. Write an equation in point-slope form for the line through the given point with the given slope. (8, -3); m = -1/4

y - 8 =-1/4(x+3)

Y-3=-1/4(x+8)

Y-3=-1/4(x-8)

Y+3=-1/4(x-8)

Two planes leave an airport at the same time, one flying east, the other flying west. the eastbound plane travels 20 mph slower. they are 1600 mi apart after 2 hr. find the speed of each plane.

The description below represents function a and the table represents function b: function a the function is 5 more than 3 times x. function b x y −1 2 0 5 1 8 which statement is correct about the slope and y-intercept of the two functions? (1 point) their slopes are equal but y-intercepts are not equal. their slopes are not equal but y-intercepts are equal. both slopes and y intercepts are equal. neither slopes nor y-intercepts are equal.

Which statements are true about additional information for proving that the triangles are congruent check all that apply
