PLEASE HEL What is the y-intercept of the line that has a slope of -1/2 and passes through the point (2, 3)?

y=-1/2x+

Explanation:

For now, let's call the y intercept b

We'll plug in x = 2 and y = 3 from the given point to find b

y = mx+b

y = (-1/2)x + b

3 = (-1/2)*2 + b

3 = -1 + b

3+1 = b

4 = b

b = 4

The y intercept is 4

The equation of the line is y = (-1/2)x + 4

answer: the resulting cross section is a rectangle. solution: a plane parallel to the base of a triangular prism will intersect a cross section that is the same shape as its bases. so the cross section is a triangle.

step-by-step explanation:

assuming this is from a math graphing problem.

7 would be on the x-axis which is the horizontal line on the graph

84 would be on the y-axis which is the vertical line on the graph
