Name a coordinate on the line y=3x+2 - Any correct point!, What line is parallel to y=2x+4 but cuts the y axis at -1? - y=2x-1, 2y=4x-9 & y=3x-1 are they parallel? - no, What is the y intercept of y=0.5x-3? - (0,-3), What is the gradient of 3y=7x+8? - 7/3, What is the midpoint of (4,9) and (1,11)? - (2.5, 10), What is the midpoint of (3,-1) and (-5,-4)? - (-1, -2.5), What is the gradient of y=mx+c? - m, y=3x-92. If x is 12 what is y? - -56, What is the equation of the line with gradient -6 and y intercept 2? - y=2-6x, Does (0,5) lie on y=5x+5? - yes, What is the gradient? - how steep a line is, What do you know about the gradients of parallel lines? - same, 4y=x+12. If x is 8 what is y? - 5, y=6(x+2). What is the y intercept? - 12, Midpoint of (-2, -4) and (3,1) - (0.5,-1.5), What line is parallel to 3y=4x-9 and has y intercept 4? - y = 4/3 x + 4, What is the gradient of the line joining (1,7) and (2,14)? - 7, Does (4,4) lie on y=-x? - no, Does (2,2) lie on 1/x? - no, y=2x(4+x). x is 3, what is y? - 42, What is the line that goes through (0,4) and (1,5)? - y = x + 4, What line is perpendicualr to y=x? - y = -x, Where does x=3 intersect the y axis? - It doesn't!,
