Write the equation of the line in slope-intercept form with slope = 1/4 and point (-8, 6)

Step-by-step explanation:

This is the standard linear equation:

represents slope and represents the y-intercept. In a finished equation, and are left as variables. and represent any given point in the function. In this case, one of the given coordinates is , and we can use this by using as and as . After plugging in known variable, the equation becomes this:

This simplifies to:

Then to:

.

After plugging in slope and y-intercept, the finished equation is:

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1
