Question

30 points!!!!!!!!!!!!!!!!!!!!!!! Help ASAP!!! 1.) Line a passes through points (-2, 1) and (2, 9). Write an equation in slope intercept form that is parallel to line a.

Answer 1

The slope calculator helps find the slope of any line through two given points. ... To find the equation of a line for any given two points that this line passes through, use our ... to calculate the slope of the line passing through the points (3,8) and (-2, 10) . ... Make sure that the points you measure from are the same as step 1.

Explanation:

Answer 2

Step 1: Use slope formula* to determine slope (or m) using both points given.

`(9 - 1)/(2 - (-2))\\\\(8)/(4) = 2`

Step 2: Use slope-intercept formula** , ONE of the points given, and the slope we just found to solve for b.

`1 = 2(-2) + b\\\\1 = -4 + b\\\\5 = b`

Step 3: Now we can set up an equation of this line in slope-intercept form.

`y = 2x + 5`

*Slope formula: y₂ - y₁/x₂ - x₁

**Slope-intercept formula: y = mx + b
