Find the intercepts by making x and y zero and solving for the other variable.
Q23 y = 4 + 2x. When x = 0 then y = 4 + 2x0 = 4. When y = 0 then 4 + 2x = 0 so x = -2
Plot the points (0, 4) and (-2, 0) and use a ruler to draw a line through them.

Q26 Use the points (0, 4) and (4, 0)

Q27 Use the points (0, 3) and (-3, 0)

Your flash has hidden part of the other questions but you could rearrange into the form y = mx + c or simply find two points that match the rule.
Q29 is different. It is a vertical line through -2 on the x-axis so it passes through (-2, 0) (-2, 2) (-2, 10) etc

CAN SOMEONE HELP ME UNDERSTAND THIS PLEASE
ICE Princess25 [194]

YEAH OFC SHAWTY!

  • so for A its -4^11 because if the powers have the same base and they are being multiplied you add the powers
  • For B its the same idea, they have the same base, and are being multiplied so you add the powers- 13^9
  • For C its similar, you have the same base, but since its Dividing, you subtract the powers. So, 9^5
  • for D you pretend like the denominator has a power of 1 and subtract. So its -24^5-24^1 which hopefully puts it into perspective of being -24^4 becuase we subtracted the powers

I cant do 2 right now, but i will in a minute

<u>And for 3 his mistake is that they arent the same bases so he cant add the powers, he should have converted them to the same base first. </u>
