Write the equation of the line through the points (6, 2) and (-9, 10) in standard form (answer)

Standard form is y=mx+b m=slope and b= y-intercept   slope = m= 10-2 = 8/-15 = -8/15                    -9-6        y=(-8/15)x+b   Use (6,2) to solve for b.   2=(-8/15)(6)+b 2=-48/15+b 78/15=b=26/5   The...

Unfortunately, I am afraid that due to the apathy many students have formed with school,... read more

What is the slope of -42x+6y=72? (answer)

-42x+6y=72   The trick to finding the slope is to remember your general linear equation: y=mx+b In this equation, m is the slope. So, for this problem you need to set everything equal to y.   Step 1: Add 42x to both sides of the equal sign. This causes 42x to...
