Is the answer (1,2)

You could also divide both dides by 3 to get 2x+1 = -1 and then slove for x. 2x=-2 x=-1 This method is quicker to do mentally

Thanks, really helpful 🎉

Excellent: Top Class Explanation, and very well presented, Fair Play

(22-4)x1/6=3

X intercept: (2, 0), Y intercept: (0, -4)

"Every straight line is going to be in the form y = mx + b" is an unhelpful rule when you consider the existence of point-slope form. And having x in the denominator is unhelpful when you consider that (y-b)/x = m is just as valid. On an exam asking students to identify the equations of straight lines without graphing them, I would certainly expect these sorts of questions. The rule should properly be explained as "every straight line can be written in the form y=mx+b".

Wow

or just use the fraction as a grouping then divide like: (6x+4)/2=11

Is it -4 good sir?

Then to find the y-intercept, calculate y when x=0 y=2(0)-4 y=0-4 y=4

Minus 2?

What do you mean how on earth do you solve it? Did you skip your fourth grade or something?

Or simple cross multiplication. Easiest way fr

Or just multiply both sides by 2 (which would be 6x+4=22) Then you subtract both sides by 4 (6x=18) Then divide both sides by 6 (x=3)

y=mx+c

No wonder i failed pre algebra 4 times. This is jibberish to me

Nice video!

Or if you like decimals 1.125

this is the dumbest way to do it, the checks are first exponents, then both x and y in denominator/xy pair

y=-1x+5? subtract x from both sides to create a slope-intercept equation

I feel u learn this in gr 1-2

This content is underrated, keep making videos man👍

5:32 Small correction: the SAT gives you a list of geometry formulas (which is basically every formula), but does not include algebra formulas, so it would help if you have the quadratic formula memorized! And if you don’t, just search up a version of the quadratic formula song and it will be seared into your brain for the rest of your life. Let me know if you have any questions about the SAT!
