Step-by-step explanation:
The slope of a graph is also known as its gradient, which is the steepness of the graph.
If we are given two points on the line, we can find the slope by taking rise/ run, which is the ratio of the change in y-coordinate against the change in the x-coordinate. This can also be written as a formula:
☆ (x₁, y₁) is the first coordinate and (x₂, y₂) is the second coordinate
In this question, we are given the equation of the line. This equation is already in the slope-intercept form (y= mx +c) since the coefficient of y is 1 and all the other terms are on the other side of the equal sign. In the slope-intercept form, m is the slope while c is the y-intercept.
m= ⅘ since the coefficient of x is ⅘ in the given equation (when the equation is in the slope-intercept form).
Notice below the picture
the one on the left-hand-side, is the 30-60-90 rule
those are the ratios, for 16), the hypotenuse (slanted side), is 4
for the ratios, that means that 4 = 2x, if you solve that for "x", that simply means "x" is 2
now, just use that value you found for "x" from the hypotenuse ratio, and use it to get the other two sides
what's the perimeter? all three sides added together
for 17)
