can you calculate the slope of the line passing through those two points? use: \(\Large slope=m=\frac{y_2y_1}{x_2x_1} \)

do you know how to use the slope formula?

would the answer be y15=3(x+2)

of course, the answer is not unique... you could've also used the other (9, 18).... :)

go ahead and post up a new question.... i don't think open study will run out of hard drive space anytime soon.

What is the equation of the given line in standard form? Use integer coefficients. y = –1.7x + 8.5

dpaIncBest ResponseYou've already chosen the best response.1
this is standard form: Ax + By = C, where A, B, C are integer coefficients... so in your slopeintercept form, we need to clear the decimals by multiplying by the whole equation by 10... \(\Large y = –1.7x + 8.5 \) \(\Large \color {red}{10}[y = –1.7x + 8.5] \) can you tell me what youd get here?
